Product details
Overview
TL022CDRG4 from Texas Instruments is a dual low-power operational amplifier in an 8-pin SOIC package, designed for battery-operated and space-constrained analog signal conditioning. It delivers 130 µA typical supply current per amplifier, 5 mV maximum input offset voltage at 25°C, and ±15 V recommended supply range - enabling precision DC-coupled amplification in portable instrumentation and sensor interfaces.
For engineers reviewing the TL022CDRG4 datasheet, TL022CDRG4 pinout, TL022CDRG4 application, or TL022CDRG4 equivalent, this page provides verified electrical parameters, thermal derating data, SOIC-8 pin mapping, real-world use cases in low-power analog front-ends, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TL022CDRG4 integrates two independent high-input-impedance op-amps with internal frequency compensation, latch-up-free operation, and output short-circuit protection. Its design supports rail-to-rail input common-mode range (±12 V) and delivers 20 VPP output swing into 10 kΩ at ±15 V supplies.
It operates across 0°C to 70°C with 0.5 MHz unity-gain bandwidth, 0.5 V/µs slew rate, and 50 nV/√Hz input voltage noise - optimized for low-frequency precision amplification rather than high-speed signal processing.

| 3 | IN+ A | Non-inverting input - accepts signals within ±12 V common-mode range |
| 4 | GND | Analog ground reference - shared return path for both amplifiers |
| 5 | IN+ B | Non-inverting input of second amplifier - electrically isolated from Channel A |
| 6 | IN– B | Inverting input of second amplifier - supports independent gain configuration |
| 7 | OUT B | Second amplifier output - enables dual-channel signal conditioning on one die |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower offset (2 mV max), higher supply current (550 µA), rail-to-rail output | Better DC accuracy but 4× higher power - unsuitable for multi-year battery life | Choose TLV2462IDR only if output swing to rail is required and power budget allows ≥500 µA per amp |
| LMV358IDR | Rail-to-rail input/output, 150 µA supply current, 1 MHz bandwidth, no short-circuit protection | Higher speed and wider input range, but lacks fault tolerance for industrial environments | Choose LMV358IDR for cost-sensitive consumer electronics where short-circuit events are unlikely |
Compared with TL022CDRG4, TLV2462IDR trades ultra-low power for improved DC performance and rail-to-rail output, while LMV358IDR offers higher bandwidth and rail compatibility at the expense of short-circuit protection - making TL022CDRG4 uniquely suited for ruggedized, long-life analog signal chains.

FAQ
What is the maximum supply voltage rating for TL022CDRG4?
The TL022CDRG4 has an absolute maximum supply voltage rating of ±18 V (36 V total), but its recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V may increase input offset drift and reduce long-term reliability, especially at elevated temperatures. The TL022CDRG4 datasheet specifies that continuous operation above ±15 V is not characterized for parametric guarantees.
Does TL022CDRG4 support rail-to-rail input or output operation?
No, TL022CDRG4 does not support rail-to-rail input or output. Its common-mode input voltage range is specified as ±12 V with ±15 V supplies, meaning inputs must stay at least 3 V away from each rail. Output swing is rated at ±10 V into 10 kΩ - approximately 2 V from each rail. For true rail-to-rail performance, consider alternatives like TLV2462IDR or LMV358IDR.
Is TL022CDRG4 RoHS compliant and lead-free?
Yes, TL022CDRG4 is RoHS compliant with lead-free terminations. Per Texas Instruments' packaging documentation, the device uses NiPdAu (nickel-palladium-gold) or NIPDAU (nickel-palladium-gold) lead finish and meets JEDEC Level-1 moisture sensitivity standards. The "G4" suffix confirms green (halogen-free) and RoHS-compliant packaging.
What is the thermal derating behavior of TL022CDRG4 in SOIC-8 package?
TL022CDRG4 in SOIC-8 (D package) has a power dissipation rating of 680 mW at TA ≤ 25°C, derating linearly at 5.8 mW/°C above 33°C ambient. At 70°C ambient, its maximum allowable power drops to 464 mW. This derating ensures junction temperature remains within safe limits under sustained load - critical for sealed enclosures or high-density PCB layouts.
Can TL022CDRG4 replace older TL022CD or TL022CP in existing designs?
Yes, TL022CDRG4 is a tape-and-reel variant of TL022CD with identical electrical specifications, SOIC-8 pinout, and 0°C to 70°C temperature rating. It replaces TL022CD directly in automated assembly; TL022CP (PDIP-8) shares functionality but requires PCB footprint change. No schematic or layout modification is needed when substituting TL022CDRG4 for TL022CD.
