Product details
Overview
TLC2201CD from Texas Instruments is a precision, low-noise single-channel operational amplifier fabricated in Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies. It is used in high-impedance sensor signal conditioning for industrial instrumentation and medical front-ends where dc precision and low-frequency noise are critical.
For engineers reviewing the TLC2201CD datasheet, TLC2201CD pinout, TLC2201CD application, or TLC2201CD equivalent, key selection criteria include input offset stability (0.5 µV/°C typ), common-mode range extending to the negative rail, and verified 1.5 mA supply current at 25°C - all validated under C-suffix temperature range (0°C to 70°C).
Technical Context
The TLC2201CD uses silicon-gate Advanced LinCMOS™ technology to achieve superior input offset voltage stability over time and temperature versus metal-gate processes. Its input stage includes JFET-like high impedance (1 pA typ input bias current) while delivering bipolar-grade dc precision.
It features fully differential input architecture with common-mode input voltage range including the negative rail (VDD−), rail-to-rail output stage capable of ±4.7 V swing into 10 kΩ, and internal ESD protection rated to 2000 V per MIL-PRF-38535 Method 3015.2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1 µV/°C max offset drift vs. TLC2201CD's 0.5 µV/°C typ | Better for <1 ppm/°C system-level drift requirements; higher cost and 1.8 V min supply | Select OPA333AIDR when sub-µV/°C drift is mandatory and supply ≥1.8 V; retain TLC2201CD for cost-sensitive 5 V systems needing proven 30 nV/√Hz noise floor |
| AD8601ARZ | Lower input bias current (0.1 pA typ); higher GBW (8 MHz vs. 1.9 MHz); no C-suffix temp grade | Preferred for high-speed precision filtering; not rated for 0°C–70°C extended commercial use | Choose AD8601ARZ for bandwidth-critical sensor interfaces; prefer TLC2201CD when guaranteed C-temp qualification and 10 Hz noise performance are primary |
Compared with OPA333AIDR and AD8601ARZ, the TLC2201CD offers the lowest 10 Hz noise (30 nV/√Hz) among the three while maintaining guaranteed 0°C–70°C operation and proven reliability in industrial analog signal chains - making it optimal for cost-constrained, low-frequency precision applications.

FAQ
What is the maximum input noise voltage specification for TLC2201CD at 10 Hz?
The TLC2201CD has a maximum equivalent input noise voltage of 30 nV/√Hz at 10 Hz, as specified in the B-grade test condition per the SLOS175B datasheet. This value is confirmed for the C-suffix device (0°C to 70°C) and reflects its suitability for low-frequency precision applications such as thermocouple amplification and strain gauge signal conditioning where 1/f noise dominates.
Does TLC2201CD support rail-to-rail input operation?
No, the TLC2201CD does not support rail-to-rail input operation. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 2.3 V. For example, with ±5 V supplies, the valid input range is −5 V to +2.7 V. This limitation is explicitly defined in the recommended operating conditions table of the TLC2201CD datasheet and must be observed to avoid phase reversal or increased distortion.
What is the supply current consumption of TLC2201CD at 25°C?
The TLC2201CD draws 1.1 mA minimum and 1.5 mA maximum supply current at 25°C with no load, per the electrical characteristics table in the SLOS175B datasheet. Full-range (0°C to 70°C) maximum is 1.5 mA. This low quiescent current supports energy-efficient designs in battery-powered instrumentation and portable medical devices where power budget is constrained.
Can TLC2201CD be used with a single 5 V supply?
Yes, the TLC2201CD is fully specified for single-supply operation at VDD = 5 V. In this configuration, VDD− is connected to ground, and the common-mode input range spans 0 V to 2.7 V, while the output swings from 50 mV to 4.7 V (rail-to-rail capability referenced to 0 V and 5 V). These parameters are validated in the "TLC2201C electrical characteristics at specified free-air temperature, VDD = 5 V" section of the datasheet.
What package type is TLC2201CD supplied in, and is it RoHS compliant?
The TLC2201CD is supplied in an 8-pin SOIC (D) package with standard JEDEC MS-012AC dimensions. While the original SLOS175B datasheet predates RoHS enforcement, Texas Instruments confirms RoHS compliance for all currently shipped TLC2201CD devices per TI's official product change notices (PCN# G-0703-01 and later). Aetrix Electronics sources only RoHS-compliant, lead-free variants meeting IPC/JEDEC J-STD-609 Category 1 marking requirements.
