How does analog chip recycling differ from digital chip recycling?

Analog chips (such as PMICs, op-amps, and ADC/DACs) use Bipolar or BiCMOS processes with older nodes (28nm-350nm) and product lifecycles of 10-20 years — unlike digital chips that iterate rapidly. Analog chip recycling runs on long-tail model matching: certain discontinued parts (like the OPA2134 or NE5532) are actually worth more than newer chips because repair-market demand is rigid while supply has dried up. Digital chips depreciate with process-node iteration; analog chips appreciate when discontinued.

What are the recycling prices for TI and ADI analog chips?

TI power management ICs such as the TPS series recycle at CNY 5-30 per piece; high-power parts like the LM5119 can reach CNY 40-80. TI precision op-amps: OPA1612 about CNY 15-25/piece, OPA627 about CNY 30-50/piece. ADI precision ADC AD9215 about CNY 80-150; ADI op-amp AD8056 about CNY 20-35. High-end parts like the ADI AD9371 RF transceiver can recycle at CNY 200-500 per piece. Batches of 1000+ pieces can command a 5-10% premium.

Which analog chip models are most worth recycling?

The three most valuable categories: First, discontinued legacy op-amps (NE5532, TL072, OPA2134) — rigid demand from audio equipment repairs. Second, server/GPU power management ICs (TI TPS536 series, Infineon IR35201) — large retirement volumes from data centers. Third, high-precision ADC/DACs (ADI AD9215, TI DAC3484) — scarce spare parts for industrial test equipment. The longer a part has been discontinued and the larger its usage volume, the higher the recycling premium.

Analog Chip Recycling: In-Depth Residual Value Analysis of TI/ADI Power Management ICs and Op-Amps

Analog Chips: The Overlooked Gold Mine of Chip Recycling

In the chip recycling industry, attention gravitates toward high-unit-price digital chips like CPUs, GPUs, and memory — but analog chips are the recycling category with the most stable per-unit residual value and the longest product lifecycle. A TI OPA627 precision op-amp that was discontinued 20 years ago has actually appreciated in price; an NE5532 remains a rigid demand item in the audio repair market today. In 2026, the global analog chip market is roughly USD 300 billion, accounting for 15-20% of total semiconductor revenue — yet recycling market penetration is under 5%. An enormous, largely untapped gold mine.

Analog vs Digital Chips: Fundamentally Different Recycling Logic

The recycling logic for analog and digital chips is completely different. Understanding this is the prerequisite for analog chip recycling:

Dimension	Digital Chips (CPU/GPU/MCU)	Analog Chips (PMIC/Op-amp/ADC)
Process node	3nm-28nm, fast iteration	28nm-350nm, slow iteration
Product lifecycle	2-5 years	10-20 years or longer
Depreciation pattern	Depreciates with node iteration	Appreciates when discontinued
Pricing logic	By performance / generation	By model match / scarcity
Per-unit value range	CNY 1-5,000+ (wide)	CNY 2-500 (concentrated)
Bulk demand source	Refurb / spare parts / teardown	Repair / spare parts / discontinued replacement

The core difference: digital chips depreciate with process iteration; analog chips appreciate when discontinued. This means the key to analog chip recycling is not "how new" but "is it discontinued" and "is there rigid repair demand."

Power Management ICs (PMICs): The Hidden Treasure in Retired Servers and GPUs

PMICs are the highest-volume, most stable category in analog chip recycling. Every server motherboard, graphics card, and network device carries dozens of PMICs — and retirement volumes are enormous. Reference recycling prices for mainstream PMICs:

Part Number	Type	Manufacturer	Reference Price (CNY) per piece
TPS53681	Server VRM multiphase controller	TI	¥30-55
TPS53679	Server VRM controller	TI	¥25-45
IR35201	Multiphase PWM controller	Infineon (IR)	¥35-60
IR35204	GPU multiphase controller	Infineon (IR)	¥30-50
MAX20810	Server VRM controller	ADI (Maxim)	¥25-45
MAX20790	Multiphase PWM controller	ADI (Maxim)	¥20-35
LM5117	Synchronous Buck controller	TI (NSC)	¥15-25
RT8209	Laptop GPU VRM	Richtek	¥5-12
NCP4200	GPU multiphase controller	onsemi	¥8-18

As the table shows, server VRM controllers carry the highest per-unit residual value (CNY 25-60) due to large retirement volumes and scarce spare-parts channels. A single server motherboard typically holds 6-12 multiphase controllers — per-board PMIC recycling value of CNY 200-500, often overlooked entirely.

Operational Amplifiers: Discontinued Old Models Are Worth More

Op-amps are the most "counterintuitive" recycling category in analog chips — older models are worth more. Reference recycling prices for classic op-amps:

Part Number	Type	Manufacturer	Reference Price (CNY) per piece	Status
NE5532	Dual op-amp (audio classic)	TI (orig. Signetics)	¥3-8	Active (many clones)
TL072/TL082	JFET-input dual op-amp	TI (orig. NSC)	¥2-6	Active
OPA2134	Burr-Brown audio op-amp	TI	¥8-15	Active
OPA1612	Precision audio op-amp	TI (BB)	¥15-25	Active
OPA627	Precision high-speed op-amp	TI (BB)	¥30-50	Partially discontinued
AD8056	High-speed op-amp	ADI	¥20-35	Active
AD8099	Ultra-low-noise op-amp	ADI	¥35-55	Active
LM4562	Ultra-low-distortion dual op-amp	TI (NSC)	¥10-18	Active

The OPA627 is a Burr-Brown-era classic; some package options have been discontinued and it recycles at a higher price than newer, in-production op-amps. The audio equipment repair market has rigid demand for these classics — a retired amplifier with 8x NE5532 + 4x OPA2134 yields about CNY 60-100 in op-amp recycling value, while scrapping the whole unit as metal would fetch less than CNY 50.

ADC/DAC Converters: Scarcity Premium on High-Precision Models

High-precision ADCs (analog-to-digital converters) and DACs (digital-to-analog converters) have low production volumes and narrow applications, giving discontinued models significant recycling premiums:

Part Number	Type	Manufacturer	Reference Price (CNY) per piece
AD9215	10-bit 105Msps ADC	ADI	¥80-150
AD9230	12-bit 250Msps ADC	ADI	¥120-200
AD9268	16-bit 125Msps ADC	ADI	¥150-250
DAC3484	16-bit 4-channel DAC	TI	¥100-180
AD9129	14-bit 5.6Gsps DAC	ADI	¥200-400
AD9371	RF transceiver (integrated ADC/DAC)	ADI	¥200-500
LTC2150	14-bit 310Msps ADC	ADI (LTC)	¥80-130
ADS1298	Medical-grade 24-bit ADC	TI	¥60-100

The ADI AD9371 RF transceiver recycles at CNY 200-500 per piece, driven by strong spare-parts demand from 5G base stations and phased-array radar. High-precision 16-bit+ ADC/DACs retired from industrial test equipment are the models recyclers should watch most closely — per-unit value can reach 10 times that of an ordinary PMIC.

Analog Chip Recycling Supply: Three Channels

Server / data center retirement: A single server motherboard carries 15-25 PMICs and 6-12 VRM controllers. Retiring 500 servers yields 7,500-12,500 PMICs with a residual value of roughly CNY 300,000-500,000.
Graphics card / GPU board teardown: High-end GPUs (e.g., RTX 4090) carry 2-4 multiphase PWM controllers + 12-20 DrMOS per card. DrMOS (e.g., IRFH series) recycles at CNY 8-15 per piece; per-GPU power-chip residual value is about CNY 150-300.
Industrial equipment / instrument retirement: Oscilloscopes, spectrum analyzers, and medical devices contain large numbers of high-precision ADC/DACs and precision op-amps. Per-device analog chip teardown value can reach CNY 500-2,000 — the most valuable analog chip supply source.

Chinese Analog Chips: Recycling Landscape

Domestic analog chip substitution is accelerating, but TI/ADI still dominate the recycling market. Chinese manufacturers' status:

SGMicro: Leading domestic PMIC and op-amp alternative; SGM2012 op-amp recycles at CNY 1-3, volumes growing.
3PEAK: Domestic precision op-amps; TP series recycles at CNY 5-12, but recycling volume remains small.
JoulWatt: Server PMIC domestic alternative; JW series recycles at CNY 8-18.
Chipsea Tech: Domestic ADC/DAC; CS series recycles at CNY 3-10.

By 2027, Chinese analog chips are expected to rise from under 5% today to 15% of the recycling market. Recyclers should build domestic part-number identification capabilities in advance.

Analog vs Digital Chip Recycling: Category Comparison

Category	Per-Unit Residual Value	Technical Barrier	2026 Supply	Margin
High-precision ADC/DAC (ADI)	CNY 80-500	Medium (functional test)	Low	35-55%
Server PMIC (TI/IR)	CNY 25-60	Low (visual + label)	Large	25-40%
Precision op-amp (TI BB/ADI)	CNY 15-55	Low	Medium	30-50%
Consumer PMIC (Richtek etc.)	CNY 3-12	Low	Very large	15-25%
Chinese analog chips	CNY 1-18	Low	Growing	10-20%

The core profit in analog chip recycling lies in model matching, not volume — recyclers who accurately identify discontinued, high-premium models can achieve margins 10-20 percentage points above the industry average.

Advice for Recyclers and Asset Disposers

Recyclers: Build an analog chip model database, with focus on identifying TI/ADI discontinued parts (OPA627, BB series, legacy ADC/DACs). A retired server motherboard's PMIC value is about CNY 200-500 — but you need model identification capability to quote accurately.
Data centers / server teardown operations: Don't focus only on CPUs and memory. Retired server motherboard PMIC + DrMOS + VRM controller combined residual value is about CNY 200-500/board, accounting for 15-25% of total board recycling value.
Industrial equipment / instrument makers: High-precision ADC/DACs in retired oscilloscopes, spectrum analyzers, and medical devices can yield CNY 500-2,000 per device in teardown value — far above scrap-metal pricing.
Audio equipment repair shops: NE5532/OPA2134/OPA627 op-amps from dismantled amplifiers and mixers have steady, rigid repair-market demand. Sort and store them by model, and batch-recycle for the best returns.
Beware counterfeits: TI/ADI high-premium models are heavily counterfeited (especially OPA627, NE5532). Use X-ray inspection and electrical parameter testing during recycling to avoid receiving fakes.
