Product details
Overview
TLC2202ID from Texas Instruments is a dual, precision, low-noise rail-to-rail output operational amplifier fabricated in Advanced LinCMOS™ technology. It delivers 500 µV max input offset voltage, 30 nV/√Hz max input voltage noise at 10 Hz, and 12 nV/√Hz max at 1 kHz, operating across −40°C to +85°C with ±2.3 V to ±8 V supply range. It is used in high-impedance sensor signal conditioning, medical instrumentation front-ends, and precision single-supply data acquisition systems.
For engineers reviewing the TLC2202ID datasheet, TLC2202ID pinout, TLC2202ID application, or TLC2202ID equivalent, key selection criteria include its rail-to-rail output swing, ultra-low 1 pA typical input bias current, common-mode input range extending to the negative rail, and guaranteed noise performance over industrial temperature range - all critical for low-level analog signal integrity in battery-powered and isolated measurement designs.
Technical Context
The TLC2202ID implements a dual-channel architecture with independent input stages optimized for low DC error and low 1/f noise. Its Advanced LinCMOS™ process enables silicon-gate MOSFET inputs, delivering input offset voltage stability of 0.5 µV/°C typ and long-term drift below 0.005 µV/month.
Each amplifier features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2), surge-current tolerance of ±100 mA on inputs/outputs, and full specification for both split-supply (±2.3 V to ±8 V) and single-supply (4.6 V to 16 V) operation with common-mode input range including the negative rail.
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 |
|---|---|---|---|
| OPA2277UA | Lower VIO (10 µV max), higher supply current (800 µA typ), bipolar input (2 nA IIB) | Better DC precision but unsuitable for >10 MΩ sources due to higher bias current | Select when ultra-low offset dominates over input impedance and power constraints |
| AD8628ARZ | Zero-drift architecture, 1 µV VIO max, 25 nV/√Hz noise at 1 kHz, 1.2 mA IDD | Superior long-term drift spec but higher quiescent current and cost | Prefer for metrology-grade calibration loops where 0.01 µV/°C drift is mandatory |
Compared with OPA2277UA and AD8628ARZ, the TLC2202ID uniquely balances ultra-low input bias current (1 pA), rail-to-rail output, and industrial temperature rating at lower cost - making it optimal for high-impedance, battery-sensitive, and thermally demanding signal chains where moderate DC precision suffices.

FAQ
What is the maximum supply voltage for the TLC2202ID?
The TLC2202ID supports a maximum supply voltage of ±8 V in split-supply mode or 16 V in single-supply mode. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ −8 V relative to the midpoint between supplies. Exceeding these limits risks permanent damage, and operation above ±8 V is not characterized or guaranteed per the SLOS175B datasheet.
Does the TLC2202ID support true single-supply operation with input referenced to ground?
Yes, the TLC2202ID supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD−/GND), allowing direct connection of ground-referenced sensors without external bias networks. When powered from a single 5 V supply (VDD+ = 5 V, VDD− = GND), inputs operate from 0 V to 2.7 V, enabling seamless interfacing with transducers tied to system ground.
What is the guaranteed input offset voltage specification for TLC2202ID over temperature?
The TLC2202ID guarantees a maximum input offset voltage of 650 µV over its full operating temperature range of −40°C to +85°C. At 25°C, the limit is 500 µV max. Its temperature coefficient is 0.5 µV/°C typical, meaning offset drift remains tightly bounded - for example, a worst-case 125°C shift from 25°C yields only ~50 µV additional drift, well within the 650 µV total budget.
Can the TLC2202ID drive capacitive loads without instability?
The TLC2202ID is unity-gain stable into capacitive loads up to 100 pF, as verified by phase margin testing (48° at unity gain with RL = 10 kΩ and CL = 100 pF). For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain stability. The device does not integrate internal compensation for larger capacitive loads.
Is the TLC2202ID pin-compatible with other devices in the TLC220x family?
Yes, the TLC2202ID uses the standard SOIC-8 (D) package and shares identical pinout with all TLC2202 variants (e.g., TLC2202ACD, TLC2202BCP) and the single-channel TLC2201ID. Pin functions - OUT1, IN1−, IN1+, VDD−/GND, IN2+, IN2−, OUT2, VDD+ - are consistent across the D-package TLC2202 family, enabling drop-in replacement within the same grade (e.g., B-grade) and temperature suffix (I-suffix).
