Product details
Overview
TL022CD from Texas Instruments is a dual low-power operational amplifier in SOIC-8 package, characterized 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 load and features internal frequency compensation, output short-circuit protection, and latch-up-free operation - ideal for battery-powered instrumentation and portable analog signal conditioning.
For engineers reviewing the TL022CD datasheet, TL022CD pinout, TL022CD application, or TL022CD 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 TL022CD 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 bipolar input stage delivers low input bias current (100–250 nA typ) and low input offset voltage (1–5 mV), while maintaining low power consumption (3.9 mW total dissipation at ±15 V).
Designed for wide-supply flexibility, it operates from ±5 V to ±15 V, supports rail-to-rail common-mode input range (±12 V), and guarantees output short-circuit protection across its full temperature range. The device avoids latch-up under all specified conditions and exhibits 0.5 MHz unity-gain bandwidth and 0.5 V/µs slew rate - balancing speed and power efficiency for precision DC-coupled and low-frequency AC applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - enables compatibility with standard dual-rail analog systems including ±12 V industrial supplies and ±5 V mixed-signal boards. |
| Input Offset Voltage (max) | 5 mV at 25°C - sets worst-case DC error floor in precision gain stages; impacts accuracy in sensor amplification and active filtering. |
| Supply Current (typ) | 130 µA per amplifier - allows dual-channel operation at ~260 µA total, supporting multi-stage battery-powered designs with >1-year runtime on coin cells. |
| Output Swing (min) | ±10 V into 10 kΩ - ensures full-scale signal delivery without clipping when driving ADC inputs or downstream buffers at ±15 V rails. |
| Unity-Gain Bandwidth | 0.5 MHz - supports stable closed-loop operation up to ~50 kHz for gain ≥ 10, suitable for anti-aliasing filters and audio preamps. |
| Slew Rate | 0.5 V/µs - limits maximum undistorted sine-wave frequency to ~80 kHz at 10 VPP, appropriate for DC–100 kHz signal conditioning. |
| Common-Mode Input Range | ±12 V - permits direct interface with sensors referenced to mid-supply or ground without level-shifting circuitry. |
Pinout & Package
TL022CD uses an 8-pin SOIC (D) package with 1.27 mm pitch, 3.9 mm width, and 1.75 mm max height - compatible with standard surface-mount assembly processes and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Provides buffered, low-impedance output of first op-amp; capable of sourcing/sinking ±6 mA with short-circuit protection. |
| 2 | Amplifier 1 Inverting Input | High-impedance node (100–250 nA bias current); used for feedback networks and inverting configurations. |
| 3 | Amplifier 1 Non-Inverting Input | High-impedance node; accepts reference voltages, sensor signals, or buffered inputs with minimal loading. |
| 4 | Negative Supply (VCC–) | Reference return for both amplifiers; must be connected to system negative rail or ground in single-supply configurations. |
| 5 | Positive Supply (VCC+) | Power rail for both amplifiers; decoupling capacitor placement near this pin is critical for stability and noise immunity. |
| 6 | Amplifier 2 Output | Independent output channel; electrically isolated from Channel 1 except through shared supply pins. |
| 7 | Amplifier 2 Inverting Input | Functionally identical to Pin 2; supports dual-channel signal processing without cross-talk in layout. |
| 8 | Amplifier 2 Non-Inverting Input | Functionally identical to Pin 3; enables simultaneous differential or parallel gain stages on one IC. |
Key Features
| Feature | Design Value |
|---|---|
| Very Low Power Consumption | 3.9 mW total dissipation at ±15 V enables dual-channel analog front-ends in energy-constrained IoT nodes and handheld meters. |
| Internal Frequency Compensation | Guarantees unity-gain stability without external capacitors - reduces BOM count and PCB area in precision instrumentation. |
| Output Short-Circuit Protection | Allows indefinite shorting to either rail or ground without damage - improves robustness in test equipment and sensor interfaces. |
| Latch-Up-Free Operation | Eliminates risk of destructive parasitic thyristor conduction during overvoltage transients or power sequencing faults. |
| Popular Dual Op-Amp Pinout | Matches industry-standard SOIC-8 layout (e.g., LM358, TL072), simplifying drop-in replacement and schematic reuse. |

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 |
|---|---|---|---|
| TL072CD | Higher slew rate (13 V/µs), lower noise (18 nV/√Hz), but higher supply current (1.4 mA per amp) and no short-circuit protection. | Preferred in audio and wideband AC-coupled circuits; unsuitable for battery life-critical or fault-prone environments. | Select TL072CD only when bandwidth/noise outweighs power and robustness requirements. |
| LM358DR | Single-supply optimized (3–32 V), lower VIO (3 mV max), but no negative rail support and slower slew rate (0.3 V/µs). | Used in cost-sensitive 0–5 V systems like Arduino shields and consumer electronics; incompatible with true dual-rail signal chains. | Choose LM358DR for single-rail, low-cost designs where ±V operation is unnecessary. |
Compared with TL022CD, TL072CD trades 5× higher power for 26× faster response and lower noise, while LM358DR sacrifices bipolar operation and short-circuit resilience for wider supply range and lower offset - making TL022CD the optimal choice for dual-rail, ultra-low-power, fault-tolerant analog signal paths.

FAQ
What is the operating temperature range for TL022CD?
The TL022CD is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade specification makes it suitable for indoor electronics, portable instruments, and non-extreme industrial environments. Unlike the military-grade TL022M variant, TL022CD does not support operation below 0°C or above 70°C - using it outside this range may result in parametric drift or failure. Always verify thermal margins in your final PCB layout and enclosure design before deployment.
Does TL022CD include internal frequency compensation?
Yes, TL022CD features fully internal frequency compensation, enabling stable unity-gain operation without external capacitors. This design eliminates the need for external compensation networks, reduces component count, and ensures consistent performance across temperature and unit-to-unit variation. The compensation is factory-trimmed and applies identically to both amplifiers within the TL022CD, supporting straightforward implementation in inverting, non-inverting, and differential configurations.
What package type and dimensions does TL022CD use?
TL022CD uses an 8-pin SOIC (Small Outline Integrated Circuit) package designated "D", measuring 3.9 mm wide, 4.9 mm long, and 1.75 mm maximum height, with 1.27 mm lead pitch. It complies with JEDEC MS-012 variation AA and is compatible with standard SMT reflow profiles (Level-1-260°C-UNLIM). The D package is supplied in tape-and-reel format (e.g., TL022CDR, 2500 units/reel), supporting automated pick-and-place assembly.
Is TL022CD pin-compatible with other dual op-amps?
Yes, TL022CD uses the industry-standard dual op-amp pinout in SOIC-8: Pins 1–4 serve Amplifier 1 (OUT, –IN, +IN, V–), Pins 5–8 serve Amplifier 2 (V+, OUT, –IN, +IN). This matches LM358, TL072, and NE5532 in D-package variants, enabling schematic and layout reuse. However, electrical differences - such as supply current, offset voltage, and short-circuit behavior - require validation in the target application before substitution.
What is the maximum supply voltage for TL022CD?
The absolute maximum supply voltage for TL022CD is ±18 V (36 V total), but the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding safe power dissipation limits and may accelerate parameter drift over time. At ±15 V, TL022CD dissipates only 3.9 mW total - well within its 464 mW rated power at 70°C ambient - ensuring reliable long-term operation without thermal derating concerns.
