Product details
Overview
TL022CDR from Texas Instruments is a dual low-power operational amplifier in an 8-pin SOIC (D) package, rated for 0°C to 70°C operation, with 5 mV max input offset voltage at 25°C, 130 µA typical supply current per amplifier, and ±15 V recommended supply range. It delivers 20 VPP output swing into 10 kΩ and features internal frequency compensation, output short-circuit protection, and latch-up-free operation - widely used in battery-powered instrumentation and sensor signal conditioning.
For engineers reviewing the TL022CDR datasheet, TL022CDR pinout, TL022CDR application, or TL022CDR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The TL022CDR integrates two independent high-input-impedance op-amps on a single die, each with internally compensated dominant-pole architecture enabling stable unity-gain operation without external components. Its low 130 µA typical supply current per amplifier and 170 µW typical power dissipation at ±2-V supplies support extended battery life in portable systems.
It operates over ±5 V to ±15 V dual supplies, supports rail-to-rail input common-mode range up to ±13 V, and delivers 0.5 V/µs slew rate with 0.5 MHz unity-gain bandwidth. Input bias currents remain below 250 nA across temperature, and output short-circuit protection is rated for unlimited duration at ≤75°C free-air temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - Enables compatibility with standard dual-rail analog signal chains and legacy industrial control rails. |
| Input Offset Voltage (max) | 5 mV at 25°C - Sets worst-case DC error floor in precision gain stages; requires <100 µV trimming for sub-mV accuracy. |
| Supply Current (typ) | 130 µA per amplifier - Allows integration of multiple amplifiers in ultra-low-power sensor front-ends without exceeding µA-level system budgets. |
| Output Swing (min) | 20 VPP into 10 kΩ - Supports full-scale signal handling in ±10 V measurement systems without clipping. |
| Slew Rate | 0.5 V/µs - Sufficient for audio-band and slow-control-loop applications; limits usable bandwidth for fast transients. |
| Unity-Gain Bandwidth | 0.5 MHz - Defines maximum closed-loop bandwidth at gain = 1; constrains settling time in buffer or follower configurations. |
| Input Bias Current (max) | 250 nA - Permits use with high-impedance sources (e.g., pH electrodes, photodiode TIA feedback) without significant offset drift. |
Pinout & Package
TL022CDR uses an 8-pin SOIC (D) package, 3.91 mm wide, 4.9 mm long, 1.75 mm max height, RoHS-compliant NIPDAU lead finish, MSL Level-1, tape-and-reel packaging (2500 pcs/reel), pin 1 quadrant Q1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Low-impedance buffered output node; capable of sourcing/sinking ±6 mA with short-circuit protection. |
| 2 | Amplifier 1 Inverting Input | Differential input terminal; high-impedance node (100–250 nA bias current) sensitive to PCB leakage paths. |
| 3 | Amplifier 1 Non-Inverting Input | Differential input terminal; identical impedance and bias behavior as Pin 2; common-mode range extends to ±13 V. |
| 4 | Ground (GND) | Reference node for both amplifiers; must be low-impedance and isolated from digital return paths to avoid noise coupling. |
| 5 | Amplifier 2 Non-Inverting Input | Second amplifier's positive input; electrically isolated from Amp1 but shares same substrate and thermal environment. |
| 6 | Amplifier 2 Inverting Input | Second amplifier's negative input; matches Pin 2 performance; enables dual-channel signal processing on one die. |
| 7 | Amplifier 2 Output | Independent output stage; no crosstalk specification provided, but layout separation minimizes inter-amplifier interference. |
| 8 | Positive Supply (VCC+) | Common positive rail connection for both amplifiers; decoupling capacitor (0.1 µF) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Very Low Power Consumption | 170 µW typical at ±2-V supplies - enables multi-op-amp designs in coin-cell-powered devices with >1-year runtime. |
| Internal Frequency Compensation | Unity-gain stable without external components - eliminates risk of oscillation in follower or gain-of-1 configurations. |
| Output Short-Circuit Protection | Unlimited duration at ≤75°C free-air temperature - prevents device failure during test, fault, or miswiring events. |
| Latch-Up-Free Operation | Guaranteed under all recommended operating conditions - avoids catastrophic failure due to transient overvoltage or ESD. |
| Popular Dual Op-Amp Pinout | Standard 8-pin DIP/SOIC layout (Pin 1 out, Pin 2/3 inputs, Pin 4 GND, Pin 5/6 inputs, Pin 7 out, Pin 8 VCC+) - simplifies board reuse and schematic symbol mapping. |
Applications
| Portable Sensor Signal Conditioning | Battery-Powered Data Acquisition Front-End |

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 22 µA supply current per amp, 6.5 mV VIO max, rail-to-rail output, but only ±3.5 V to ±8 V supply range. | Preferred for sub-5 V battery systems; unsuitable for ±12 V industrial signal chains requiring wider headroom. | Select TLV2462IDR when supply is limited to 3.3 V or 5 V and rail-to-rail output swing is critical; retain TL022CDR for ±15 V legacy compatibility. |
| LM358DR | Higher 700 µA supply current per amp, 7 mV VIO max, no short-circuit protection rating, wider –25°C to 85°C temp range. | Cost-optimized general-purpose use; lacks guaranteed unlimited short-circuit survival and low-temp stability of TL022CDR. | Choose LM358DR for non-critical consumer applications where power budget exceeds 1 mA; TL022CDR remains preferred for battery longevity and robustness. |
Compared with TLV2462IDR and LM358DR, the TL022CDR uniquely balances ultra-low quiescent current (130 µA), ±15 V supply tolerance, and guaranteed short-circuit survivability - making it the only option among the three qualified for long-life, wide-supply, fault-tolerant analog sensing.

FAQ
What is the operating temperature range for TL022CDR?
The TL022CDR is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating is explicitly defined in the datasheet's "AVAILABLE OPTIONS" table and confirmed in the "recommended operating conditions" section. The TL022CDR variant uses the SOIC (D) package and does not support the extended –55°C to 125°C range offered by the TL022M military-grade version. Thermal derating begins above 25°C per the Dissipation Rating Table.
Does TL022CDR have internal frequency compensation?
Yes, the TL022CDR includes internal frequency compensation, as stated in both the "Features" list and the "description" section of the datasheet. This design ensures unity-gain stability without requiring external compensation components, simplifying circuit design and improving reliability in follower, integrator, and low-gain configurations where phase margin is critical.
What is the maximum input offset voltage for TL022CDR at 25°C?
The maximum input offset voltage for TL022CDR at 25°C is 5 mV, as specified in the "AVAILABLE OPTIONS" table under "VIOmax AT 25°C" for the TL022CD part number. This value is confirmed in the "electrical characteristics" table, where TL022C shows a 5 mV max at 25°C under test condition VO = 0 and RS = 50 Ω.
Is TL022CDR pin-compatible with other dual op-amps in SOIC-8 packages?
The TL022CDR follows the "popular dual operational amplifier pinout" defined in the datasheet: Pin 1 (1OUT), Pin 2 (1IN–), Pin 3 (1IN+), Pin 4 (GND), Pin 5 (2IN+), Pin 6 (2IN–), Pin 7 (2OUT), Pin 8 (VCC+). This matches industry-standard SOIC-8 dual op-amp layouts including LM358, TL082, and NE5532, enabling direct footprint reuse in many designs - though electrical parameters differ significantly.
What packaging format is used for TL022CDR?
TL022CDR is supplied in tape-and-reel format, with 2500 units per reel, as explicitly stated in the "PACKAGE OPTION ADDENDUM" and "TAPE AND REEL INFORMATION" sections. The SOIC (D) package has reel diameter 330.0 mm, reel width 12.4 mm, and pin 1 orientation in quadrant Q1 - conforming to JEDEC MS-012 variation AA and supporting automated SMT placement.
