Product details
Overview
TLC2201ACD from Texas Instruments is a precision, low-noise single-channel operational amplifier using Advanced LinCMOS™ process. It delivers 200 µV max input offset voltage, 30 nV/√Hz max input noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies. It is designed for high-impedance sensor signal conditioning in single- or split-supply instrumentation systems.
For engineers reviewing the TLC2201ACD datasheet, TLC2201ACD pinout, TLC2201ACD application, or TLC2201ACD equivalent, this page provides verified specifications, package mapping, functional alternatives, and design-critical performance context - including noise floor, offset stability, common-mode range (down to negative rail), and ESD robustness up to 2000 V.
Technical Context
The TLC2201ACD implements a silicon-gate LinCMOS™ architecture that combines JFET-level input impedance (>1012 Ω) with bipolar-grade DC precision. Its input stage includes matched P-channel MOSFETs enabling rail-inclusive common-mode operation and sub-picoamp bias current (1 pA typ).
Internally compensated for unity-gain stability, it achieves 1.9 MHz gain-bandwidth product and 2.7 V/µs slew rate while maintaining 48° phase margin into 10 kΩ//100 pF loads. The device is fully specified across 0°C to 70°C and supports both single-supply (e.g., 5 V with GND as VDD−) and dual-supply configurations.

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 auto-zero architecture; 10 µV max VIO; higher quiescent current (17 µA); 350 kHz GBW | Better DC accuracy but lower bandwidth and higher noise above 10 Hz (5.5 µVPP, 0.1–10 Hz) | Select when ultra-low offset and drift dominate over low-frequency noise and bandwidth requirements |
| AD8628ARZ | Zero-drift; 6 µV max VIO; 2.5 MHz GBW; 1.5 µVPP (0.1–10 Hz); higher supply current (1.2 mA) | Superior AC performance and lower integrated noise, but less optimized for ultra-low 10-Hz noise | Prefer for multi-kHz sensor interfaces needing both low offset and wider bandwidth than TLC2201ACD offers |
Compared with OPA333AIDR and AD8628ARZ, the TLC2201ACD trades zero-drift DC precision for significantly lower 10-Hz noise (30 nV/√Hz vs >100 nV/√Hz) and lower cost, making it optimal for DC- to low-kHz precision analog front-ends where 1/f noise dominates system error.

FAQ
What is the maximum input noise voltage specification for TLC2201ACD at 10 Hz?
The TLC2201ACD has a maximum equivalent input noise voltage of 30 nV/√Hz at 10 Hz, as specified in the official Texas Instruments datasheet SLOS175B. This value is measured under standard conditions (VDD± = ±5 V, TA = 25°C) and defines its suitability for ultra-low-noise, low-frequency signal amplification tasks. The TLC2201ACD achieves this performance through its Advanced LinCMOS™ input stage, distinguishing it from standard CMOS op-amps.
Does TLC2201ACD support single-supply operation?
Yes, the TLC2201ACD is fully specified for single-supply operation - for example, with VDD+ = 5 V and VDD− tied to GND. Its common-mode input voltage range extends to the negative rail (GND), and its rail-to-rail output swings within 300 mV of both supply rails. This enables direct interfacing with ground-referenced sensors without level-shifting circuitry, as confirmed in the "Recommended Operating Conditions" and "Electrical Characteristics" tables of the TLC2201ACD datasheet.
What is the operating temperature range for TLC2201ACD?
The TLC2201ACD is characterized for operation from 0°C to +70°C, denoted by its "C" suffix. This commercial-grade temperature range is validated across all key parameters including input offset voltage, noise, CMRR, and supply current. The datasheet confirms full specification compliance across this range, with derating applied only for power dissipation above 25°C ambient - ensuring predictable performance in office, lab, and non-extreme industrial environments.
How does the input bias current of TLC2201ACD compare to bipolar op-amps?
The TLC2201ACD exhibits a typical input bias current of 1 pA at 25°C - over six orders of magnitude lower than typical bipolar op-amps (e.g., LM741: ~80 nA). This ultra-low bias current results from its MOSFET input stage and enables high-impedance sensor interfacing (e.g., pH electrodes, piezoelectric elements) without significant voltage error or signal loading. The datasheet guarantees ≤100 pA across the full 0°C to 70°C range, confirming robustness for precision analog designs.
Is TLC2201ACD pin-compatible with other devices in the TLC220x family?
Yes, the TLC2201ACD shares the same SOIC-8 (D) package and pinout with TLC2201BCD, TLC2201CD, and TLC2201ID - all feature identical Pin 1 (IN−), Pin 2 (IN+), Pin 3 (OUT), Pin 4 (VDD−), Pin 7 (VDD+), and NC pins. However, performance grades differ: TLC2201ACD offers tighter VIO (200 µV max) and lower noise than TLC2201CD (500 µV/35 nV/√Hz), so direct substitution requires validation against system-level offset and noise budgets.
