Product details
Overview
TL022CPSRG4 from Texas Instruments is a dual low-power operational amplifier in SO (PS) package, designed for battery-operated and low-supply-current analog systems. It delivers 130 µA typical supply current per amplifier, 5 mV maximum input offset voltage at 25°C, and ±15 V recommended supply range. Its internal frequency compensation, output short-circuit protection, and latch-up-free operation support reliable use in precision sensor interfaces and portable instrumentation.
For engineers reviewing the TL022CPSRG4 datasheet, TL022CPSRG4 pinout, TL022CPSRG4 application, or TL022CPSRG4 equivalent, key selection considerations include its 0°C to 70°C operating range, SO-8 packaging with NIPDAU lead finish, low 170 µW typical power dissipation at ±2-V supplies, and compatibility with single- or dual-supply configurations up to ±15 V.
Technical Context
The TL022CPSRG4 implements two independent high-input-impedance op-amps with internally compensated dominant-pole architecture, enabling stable unity-gain operation without external components. Its input stage uses JFET-based differential pairs to achieve low input bias current (100–250 nA typ) and low input offset current (15–80 nA typ).
Each amplifier features rail-to-rail input common-mode range (±12 V min), 20 VPP output swing into 10 kΩ, 0.5 MHz unity-gain bandwidth, and 0.5 V/µs slew rate. Output short-circuit protection operates continuously across the full temperature range, and absolute maximum supply ratings reach ±18 V for the TL022C variant.

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 |
|---|---|---|---|
| LM358DR | Higher supply current (700 µA typ), wider offset voltage range (7 mV max), no guaranteed latch-up immunity | Less suitable for ultra-low-power battery systems; acceptable in cost-sensitive AC-powered designs | Choose LM358DR only when higher drive capability or lower cost outweighs power and reliability requirements |
| TLV2462IDR | Lower offset (2 mV max), rail-to-rail output, 650 µA supply current, 2.5 V to 6 V single-supply only | Optimized for modern low-voltage microcontroller interfaces, not compatible with ±15 V legacy systems | Prefer TLV2462IDR for new 3.3 V designs requiring improved DC accuracy, but verify supply compatibility |
Compared with LM358DR and TLV2462IDR, TL022CPSRG4 uniquely balances ultra-low quiescent current, wide dual-supply operation (±15 V), and proven latch-up immunity - making it the preferred choice for retrofitting legacy industrial analog signal paths while maintaining long battery life.

FAQ
What is the maximum supply voltage rating for TL022CPSRG4?
The TL022CPSRG4 has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC– terminals. This allows safe operation with dual supplies up to ±15 V (recommended) and transient tolerance within specification limits. Exceeding ±18 V risks permanent damage, and operation above ±15 V is not characterized for performance parameters such as offset or bandwidth.
Does TL022CPSRG4 support single-supply operation?
Yes, TL022CPSRG4 supports true single-supply operation from +5 V to +15 V with ground referenced at pin 4. Its input common-mode range extends to within 1.5 V of the negative rail (GND), and output can swing to within ~2 V of GND and ~1.5 V of VCC+, enabling use in 3.3 V–compatible circuits with appropriate level-shifting or rail-splitting networks.
Is TL022CPSRG4 pin-compatible with other dual op-amps like LM358?
TL022CPSRG4 uses the industry-standard 8-pin SOIC pinout matching LM358, TL082, and NE5532 in D/P/PS packages - pin 1 is OUT A, pin 2 is IN– A, pin 3 is IN+ A, pin 4 is GND, pin 5 is IN+ B, pin 6 is IN– B, pin 7 is OUT B, and pin 8 is VCC+. However, differences in input stage topology and supply current mean electrical behavior may vary in high-precision or high-speed circuits.
What does the "G4" suffix indicate in TL022CPSRG4?
The "G4" suffix in TL022CPSRG4 denotes a specific TI manufacturing and assembly variant compliant with JEDEC standards, featuring NiPdAu (NIPDAU) lead finish, Level-1 moisture sensitivity rating, and tape-and-reel packaging (2000 units per reel). It confirms RoHS compliance and qualifies the part for standard SMT reflow profiles up to 260°C peak temperature.
How does TL022CPSRG4 handle output short-circuit conditions?
TL022CPSRG4 includes internal output short-circuit protection rated for unlimited duration when the device case temperature remains ≤75°C. This protection activates automatically during shorts to GND or either supply rail, limiting current to ±6 mA typical without requiring external foldback circuitry - a critical feature for unattended remote sensor nodes.
