Product details
Overview
TLC2201IDR 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 input noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies across −40°C to +85°C. It serves as a high-impedance signal conditioner in sensor front-ends and medical instrumentation.
For engineers reviewing the TLC2201IDR datasheet, TLC2201IDR pinout, TLC2201IDR application, or TLC2201IDR equivalent, this page provides verified specifications, package mapping, real-world use cases, and validated alternative options for low-noise, precision DC-coupled amplification in single- or split-supply systems.
Technical Context
The TLC2201IDR uses silicon-gate Advanced LinCMOS™ technology to achieve superior input offset voltage stability over temperature (0.5 µV/°C typ) and time versus metal-gate alternatives. Its input stage includes JFET-like high impedance (1 pA typ input bias current) while delivering bipolar-grade DC precision.
It features a common-mode input voltage range extending to the negative rail and rail-to-rail output swing - enabling true single-supply operation down to 4.6 V total supply. Internal ESD protection withstands 2000 V per MIL-PRF-38535 Method 3015.2, and inputs/outputs tolerate −100 mA surge currents without latch-up.

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. TLC2201IDR's 0.5 µV/°C; higher quiescent current (17 µA vs. 1.5 mA) | Better for ultra-stable DC gain stages where long-term drift dominates; less suitable for high-output-drive requirements | Select OPA333AIDR when sub-µV drift is mandatory; retain TLC2201IDR for rail-to-rail output drive >±20 mA |
| AD8603ARZ-REEL7 | Lower input noise (12 nV/√Hz @ 1 kHz); wider GBW (8 MHz); but only 1.8–5.5 V single-supply operation | Preferred for battery-powered portable instruments needing wide bandwidth; incompatible with ±5 V or 12 V systems | Choose AD8603ARZ-REEL7 for low-voltage, high-speed sensing; TLC2201IDR remains optimal for industrial ±5 V/±8 V designs |
Compared with OPA333AIDR and AD8603ARZ-REEL7, the TLC2201IDR uniquely balances rail-to-rail output drive capability (±50 mA), extended supply range (±2.3 V to ±8 V), and proven industrial temperature performance (−40°C to +85°C) without zero-drift complexity or voltage limitations.

FAQ
What is the maximum supply voltage for TLC2201IDR?
The TLC2201IDR has an absolute maximum supply voltage rating of ±8 V. Operation beyond this risks permanent damage. Recommended operating range is ±2.3 V to ±8 V for dual-supply use, or 4.6 V to 16 V for single-supply configurations. Always observe derating curves in the datasheet for thermal management at elevated ambient temperatures.
Does TLC2201IDR support true single-supply operation with input referenced to ground?
Yes. The TLC2201IDR's common-mode input voltage range includes the negative rail (VDD−), allowing its IN+ and IN− pins to accept signals down to ground in single-supply configurations. Combined with rail-to-rail output swing, this enables fully ground-referenced signal chains without level-shifting circuitry - ideal for interfacing with resistive sensors or transducers.
What is the input noise performance of TLC2201IDR at low frequencies?
The TLC2201IDR delivers 30 nV/√Hz maximum equivalent input noise voltage at 10 Hz and 12 nV/√Hz maximum at 1 kHz (B-grade). Its 1/f noise corner is well below 10 Hz, making it suitable for precision DC and sub-100 Hz applications such as ECG, pH sensing, and thermopile amplification where low-frequency noise dominates system error.
Can TLC2201IDR drive heavy capacitive loads?
The TLC2201IDR is unity-gain stable with capacitive loads up to 100 pF when driving a 10 kΩ load, as confirmed by phase margin testing (48° at unity gain). For larger capacitive loads (>100 pF), external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain stability and prevent peaking or oscillation in precision sensor interfaces.
Is TLC2201IDR pin-compatible with other devices in the TLC220x family?
Yes. The TLC2201IDR shares identical 8-pin SOIC (D) pinout with all TLC2201x variants (e.g., TLC2201CD, TLC2201BID) and is functionally compatible with TLC2202x dual-amplifier variants in pin-for-pin layout - though channel count differs. This allows drop-in substitution within the same package footprint when single-channel performance meets system requirements.
