Product details
Overview
TL022CP from Texas Instruments is a dual low-power operational amplifier in an 8-pin PDIP package, rated for 0°C to 70°C operation. It delivers 5 mV max input offset voltage, 130–250 µA typical supply current per amplifier, and ±15 V max supply voltage. Designed for battery-powered analog signal conditioning, it features internal frequency compensation, output short-circuit protection, and latch-up-free operation.
For engineers reviewing the TL022CP datasheet, TL022CP pinout, TL022CP application, or TL022CP equivalent, key selection criteria include its low 170 µW typical power dissipation at ±2-V supplies, 0.5 MHz unity-gain bandwidth, and compatibility with single- or dual-supply configurations in precision sensor interfaces and portable instrumentation.
Technical Context
The TL022CP implements two independent high-input-impedance op-amps on a single silicon die, each 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).
It supports rail-to-rail common-mode input voltage range (±12 V min), delivers ±6 mA short-circuit output current, and maintains 60–80 dB large-signal voltage gain across temperature. The device operates with supply voltages as low as ±5 V and up to ±15 V, making it suitable for legacy industrial and portable systems requiring low quiescent power without sacrificing DC accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - Enables use in both low-voltage battery systems and standard ±12 V industrial rails. |
| Input Offset Voltage (max) | 5 mV at 25°C - Sets baseline DC error budget for precision DC-coupled amplification stages. |
| Supply Current (typ) | 130 µA per amplifier - Enables multi-channel analog front-ends with sub-300 µA total quiescent draw. |
| Unity-Gain Bandwidth | 0.5 MHz - Supports audio-frequency and slow-control-loop applications with adequate phase margin. |
| Input Bias Current (typ) | 100 nA - Allows high-impedance sensor interfacing (e.g., thermistors, photodiodes) without significant loading error. |
| Output Short-Circuit Current | ±6 mA - Provides robust fault tolerance during transient overloads without latch-up or damage. |
| Common-Mode Input Range | ±12 V - Permits direct connection to signals referenced near supply rails in single-supply configurations. |
Pinout & Package
TL022CP is housed in an 8-pin plastic dual in-line package (PDIP-P), with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; leads are tin-lead (NIPDAU) finished and rated for 260°C reflow (10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Provides buffered, low-impedance output signal; capable of sourcing/sinking ±6 mA. |
| 2 | Inverting Input of Amplifier 1 | Differential input node; high impedance (≥10¹² Ω) enables minimal signal loading. |
| 3 | Non-Inverting Input of Amplifier 1 | Reference input for follower or summing configurations; matched to Pin 2 for CMRR optimization. |
| 4 | Ground / Negative Supply | Common return path for both amplifiers; must be low-impedance to minimize noise coupling. |
| 5 | Non-Inverting Input of Amplifier 2 | Independent input for second channel; electrically isolated but thermally coupled to Amp 1. |
| 6 | Inverting Input of Amplifier 2 | Second differential pair input; shares same bias network topology as Pin 2. |
| 7 | Output of Amplifier 2 | Independent output stage; identical performance specs to Pin 1 under matched load conditions. |
| 8 | Positive Supply | Power rail for both amplifiers; decoupling capacitor required within 1 cm for stability. |
Key Features

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 |
|---|---|---|---|
| LM358P | Higher input offset voltage (7 mV max), higher supply current (500 µA typ), no internal ESD protection diodes on inputs. | Less suitable for high-impedance sensor nodes; acceptable for cost-sensitive non-precision applications. | Choose LM358P only when absolute lowest cost is critical and 5 mV offset margin is acceptable. |
| TLV2462CP | Lower supply current (23 µA typ), rail-to-rail output, but narrower supply range (2.7–6 V) and no ±15 V support. | Optimized for modern low-voltage battery systems; incompatible with legacy ±12 V or ±15 V designs. | Choose TLV2462CP only for new 3.3 V or 5 V designs where rail-to-rail output swing is required. |
Compared with LM358P and TLV2462CP, TL022CP uniquely balances ±15 V operation, 5 mV offset, and sub-250 µA supply current in a legacy-compatible PDIP package-making it the only viable option for upgrading aging ±12 V analog systems without redesigning power rails or layout.

FAQ
What is the maximum operating temperature range for TL022CP?
The TL022CP is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating is specified in the official Texas Instruments SLOS076 datasheet and confirmed across all active ordering variants including TL022CP and TL022CPSRG4. Exceeding 70°C ambient may cause parametric shift beyond guaranteed limits, particularly in input offset voltage and supply current.
Does TL022CP support single-supply operation?
Yes, TL022CP supports single-supply operation with appropriate biasing. Its common-mode input voltage range extends to ±12 V (minimum), allowing inputs to swing within 3 V of either rail when powered from +15 V and GND. For true single-supply use, a mid-rail reference (e.g., VCC/2) must be applied to the non-inverting input to establish DC operating point, as the device lacks rail-to-rail input capability.
What is the input offset voltage specification for TL022CP?
The TL022CP has a maximum input offset voltage of 5 mV at 25°C, with typical value of 1 mV. This parameter is guaranteed across the full 0°C to 70°C operating range, where the max increases to 7.5 mV. The specification applies independently to each amplifier and is measured with zero output voltage and 50 Ω source resistance, per the SLOS076 datasheet test conditions.
Is TL022CP pin-compatible with other dual op-amps in PDIP-8 packages?
Yes, TL022CP uses the industry-standard dual op-amp pinout: Pin 1 = Amp1 Out, Pin 2 = Amp1 In–, Pin 3 = Amp1 In+, Pin 4 = V–/GND, Pin 5 = Amp2 In+, Pin 6 = Amp2 In–, Pin 7 = Amp2 Out, Pin 8 = V+. This matches LM358, TL082, and NE5532 in PDIP-8, enabling direct PCB replacement where electrical specs align.
What packaging options are available for TL022CP?
TL022CP is supplied in 8-pin plastic dual in-line package (PDIP-P) in tube format, with 50 units per tube. The part marking is "TL022CP", and lead finish is NIPDAU. Unlike SOIC variants (e.g., TL022CDR), TL022CP does not ship in tape-and-reel; it is exclusively offered in tube packaging for through-hole assembly and prototyping use cases.
