Product details
Overview
TL022CPSR from Texas Instruments is a dual low-power operational amplifier in an 8-pin SO (PS) package, characterized for 0°C to 70°C operation. It delivers 130 µA typical supply current per amplifier, 5 mV max input offset voltage at 25°C, and 0.5 MHz unity-gain bandwidth - enabling precision, battery-friendly analog signal conditioning in portable instrumentation and sensor interfaces.
For engineers reviewing the TL022CPSR datasheet, TL022CPSR pinout, TL022CPSR application, or TL022CPSR equivalent, key selection criteria include its low 3.9 mW total dissipation at ±15 V, internal frequency compensation, output short-circuit protection, and compatibility with single- or split-supply configurations down to ±5 V.
Technical Context
The TL022CPSR integrates two independent high-input-impedance op-amps on a single die, each featuring internal frequency compensation for stable unity-gain operation without external components. Its bipolar input stage enables low input bias current (100–250 nA typ) and low input offset voltage (1–5 mV), supporting DC-coupled precision amplification.
Designed for low-power analog systems, it operates across ±5 V to ±15 V supplies, supports rail-to-rail input common-mode range (±12 V), and delivers 20 VPP output swing into 10 kΩ. Latch-up-free construction and unlimited output short-circuit duration enhance reliability in industrial and embedded environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports dual-supply operation in legacy analog systems and battery-powered designs with headroom for signal swing. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures ≤0.5% gain error in unity-gain buffer or inverting amplifier configurations at room temperature. |
| Supply Current (typ) | 130 µA per amplifier - enables multi-channel analog front-ends with sub-300 µA total quiescent draw, critical for coin-cell applications. |
| Unity-Gain Bandwidth | 0.5 MHz - suitable for audio preamplification, sensor signal conditioning, and low-frequency active filtering up to ~50 kHz. |
| Output Short-Circuit Duration | Unlimited - allows safe operation in fault-prone circuits (e.g., transducer interfaces) without thermal shutdown or latch-up risk. |
| Common-Mode Input Range | ±12 V - accepts inputs within 3 V of either rail, enabling direct interfacing with ±10 V industrial sensors and DAC outputs. |
| Slew Rate | 0.5 V/µs - limits large-signal settling time to ~40 µs for 20 V step, appropriate for slow-varying process signals and control loops. |
Pinout & Package
TL022CPSR uses an 8-pin Small Outline (SO) package with PS drawing, 1.75 mm max height, 12.0 mm reel width, and Q1 pin-1 orientation per JEDEC MS-012 variation AA. Pin 1 is marked by a beveled corner and located at the top-left when viewed from the top with the marking side up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier 1) | Accepts feedback network connection; high-impedance node requiring guarded layout to minimize leakage-induced offset drift. |
| 2 | Non-inverting input (Amplifier 1) | Reference point for differential sensing; common-mode voltage must stay within ±12 V of midpoint between supplies. |
| 3 | Output (Amplifier 1) | Capable of sourcing/sinking ±6 mA; drives 10 kΩ loads to ±10 V with <5% overshoot and 0.3 µs rise time. |
| 4 | Negative supply (VCC–) | Reference for both amplifiers' internal biasing; must be decoupled with ≥0.1 µF ceramic capacitor near the pin. |
| 5 | Positive supply (VCC+) | Power rail for both amplifiers; shared supply rejection ratio (60 dB min) applies across full operating temperature range. |
| 6 | Output (Amplifier 2) | Independent output stage with identical specs to Pin 3; enables dual-channel signal processing without cross-talk. |
| 7 | Inverting input (Amplifier 2) | Electrically isolated from Amplifier 1 inputs; no internal coupling - supports fully independent dual-amplifier topologies. |
| 8 | Non-inverting input (Amplifier 2) | Matches Pin 2 performance; allows simultaneous conditioning of two sensor channels with matched DC accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 3.9 mW total dissipation at ±15 V enables >1-year operation on CR2032 batteries in always-on sensor nodes. |
| Internal frequency compensation | Guarantees stable unity-gain operation without external compensation capacitors - reduces BOM count and layout complexity. |
| Output short-circuit protection | Withstands indefinite short to either supply rail, eliminating need for external current-limiting resistors in transducer driver stages. |
| Latch-up-free operation | Prevents destructive parasitic thyristor activation during overvoltage transients - improves field reliability in noisy industrial settings. |
| Popular dual op-amp pinout | Matches industry-standard 8-pin DIP/SO layout (e.g., LM358, TL072), allowing drop-in replacement in existing PCB footprints. |

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 VIO range (7 mV max), no guaranteed latch-up immunity. | Less suitable for ultra-low-power battery operation but more tolerant of wide supply variations (3–32 V). | Choose LM358DR only when extended supply range or cost sensitivity outweighs power and reliability requirements. |
| TLV2462IDR | Rail-to-rail I/O, lower VIO (1.5 mV max), higher supply current (550 µA typ), CMOS input (pA bias). | Enables true single-supply operation and higher-precision DC coupling but increases quiescent power 4× over TL022CPSR. | Choose TLV2462IDR when rail-to-rail output swing or sub-mV offset is mandatory, accepting higher power budget. |
Compared with LM358DR and TLV2462IDR, TL022CPSR uniquely balances ultra-low power (130 µA), bipolar-input precision (5 mV VIO), and robustness (unlimited short-circuit, latch-up-free) - making it optimal for legacy-compatible, long-life industrial and medical analog signal chains where supply headroom and reliability are prioritized over rail-to-rail operation.

FAQ
What is the maximum operating temperature range for TL022CPSR?
The TL022CPSR is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with its SO (PS) package and intended use in non-military, non-automotive applications such as portable instrumentation and industrial control panels. The military-grade TL022M variant extends to –55°C to 125°C but uses different packages (JG or U) and is not recommended for new designs.
Does TL022CPSR support single-supply operation?
Yes, TL022CPSR supports single-supply operation with appropriate biasing. Its input common-mode range extends to ±12 V relative to the supply midpoint, meaning it can operate from +5 V to +30 V single supplies if the input signal is referenced to VCC/2. However, output swing remains limited to ~3 V from each rail, so full rail-to-rail capability requires external level-shifting or a different amplifier family.
What is the pinout compatibility of TL022CPSR with other dual op-amps?
TL022CPSR uses the industry-standard 8-pin SOIC pinout (Pin 1 = IN– Amp1, Pin 2 = IN+ Amp1, Pin 3 = OUT Amp1, Pin 4 = V–, Pin 5 = V+, Pin 6 = OUT Amp2, Pin 7 = IN– Amp2, Pin 8 = IN+ Amp2), matching LM358, TL072, and NE5532. This allows direct PCB footprint reuse in legacy designs, though electrical parameters (e.g., supply current, offset voltage) differ and require verification in the target circuit.
Is TL022CPSR RoHS compliant and lead-free?
Yes, TL022CPSR is RoHS compliant and features NiPdAu (NIPDAU) lead finish. Per TI's packaging documentation, it carries MSL Level-1 rating with unlimited floor life and peak reflow tolerance of 260°C, meeting IPC/JEDEC J-STD-020 standards for lead-free assembly. The "G4" suffix variants (e.g., TL022CPSRG4) denote alternate lead-finish options, but TL022CPSR itself is standard NIPDAU.
How does TL022CPSR handle output short-circuit conditions?
TL022CPSR provides unlimited-duration output short-circuit protection to either supply rail or ground under all operating conditions within its specified temperature range (0°C to 70°C). This is achieved via internal current limiting and thermal foldback, eliminating the need for external series resistors in sensor driver or actuator interface circuits - a key reliability feature distinguishing it from many contemporary low-power op-amps.
