Product details
Overview
TLC2202BID from Texas Instruments is a dual precision, low-noise operational amplifier using Advanced LinCMOS™ process, designed for high-impedance signal conditioning in single- or split-supply systems. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, −40°C to +85°C operating range, and 1.8–2.7 mA supply current per amplifier.
For engineers reviewing the TLC2202BID datasheet, TLC2202BID pinout, TLC2202BID application, or TLC2202BID equivalent, this page provides verified specifications, package mapping (SOIC-8), functional pin definitions, real-world use cases in sensor front-ends and medical instrumentation, and two validated alternative parts with documented technical and application differences.
Technical Context
The TLC2202BID integrates two independent precision op-amps on a single die using silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature and time versus metal-gate processes. Its input stage includes common-mode range extending to the negative rail and ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2).
Each amplifier features internal compensation, unity-gain stable operation, and robust output drive capability (±50 mA). The device supports ±2.3 V to ±8 V dual-supply or +4.6 V to +16 V single-supply operation, with rail-to-rail output swing delivering >4.7 V peak positive and <−4.7 V peak negative swing into 10 kΩ at ±5 V supplies.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2202ACD | 200 µV max input offset voltage (vs. 500 µV), same noise and rail-to-rail output | Better DC accuracy for µV-level DC measurements; identical AC performance and pinout | Select when VIO budget is ≤200 µV and cost premium is acceptable |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.02 µV/°C drift, but higher 5.5 nV/√Hz noise at 1 kHz | Superior long-term stability for calibration-critical systems; less suitable for low-frequency noise-sensitive apps | Choose for zero-drift requirements where 1/f noise below 10 Hz is not dominant |
Compared with TLC2202ACD and OPA2333AIDR, the TLC2202BID offers optimal balance of low 1/f noise, moderate DC precision, and proven reliability in industrial temperature ranges-making it preferred for sensor front-ends where noise dominates error budgets more than initial offset.

FAQ
What is the maximum supply voltage for TLC2202BID?
The TLC2202BID supports dual-supply operation from ±2.3 V to ±8 V, or single-supply operation from +4.6 V to +16 V. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ −8 V. Exceeding these limits risks permanent damage, and operation above ±8 V violates the recommended operating conditions defined in the SLOS175B datasheet.
Does TLC2202BID support rail-to-rail input?
No, the TLC2202BID does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but only up to VDD+ − 2.3 V. For example, at ±5 V supplies, the valid input range is −5 V to +2.7 V. This design prioritizes low noise and precision over full rail-to-rail input capability.
What is the guaranteed input offset voltage specification for TLC2202BID?
The TLC2202BID is specified with a maximum input offset voltage of 500 µV at 25°C and 650 µV across the full −40°C to +85°C operating range. This value is tested and guaranteed per the B-grade screening defined in the SLOS175B datasheet, distinguishing it from the tighter 200 µV limit of the A-grade TLC2202ACD variant.
Can TLC2202BID drive capacitive loads directly?
The TLC2202BID is unity-gain stable and characterized with CL = 100 pF in the datasheet, but driving larger capacitive loads (>500 pF) without isolation resistance may cause peaking or oscillation. For loads exceeding 200 pF, a series resistor (typically 10–100 Ω) between the output and capacitance is recommended to maintain phase margin ≥48° and prevent instability.
Is TLC2202BID pin-compatible with other TLC2202 variants?
Yes, all TLC2202 variants-including TLC2202ACD, TLC2202BCD, TLC2202BID, and TLC2202BMD-share identical SOIC-8 (D) package pinout and electrical pin functions. Differences are limited to grade-specific parameters (e.g., VIO, noise) and temperature range qualification; no PCB layout change is needed when substituting within the TLC2202 family.
