Texas Instruments TLC2201AID

Overview

TLC2201AID from Texas Instruments is a precision, low-noise single operational amplifier using Advanced LinCMOS™ process. It delivers 30 nV/√Hz max input noise at 10 Hz, 500 µV max input offset voltage, rail-to-rail output swing, and operates across −40°C to +85°C. It serves in high-impedance sensor signal conditioning and precision analog front-ends for data acquisition systems.

For engineers reviewing the TLC2201AID datasheet, TLC2201AID pinout, TLC2201AID application, or TLC2201AID equivalent, key selection criteria include its low 1 pA typical input bias current, common-mode input range extending to the negative rail, and guaranteed noise performance over industrial temperature range - critical for low-level DC-coupled amplification.

Technical Context

The TLC2201AID implements a dual-stage CMOS input stage with silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over time and temperature versus metal-gate alternatives. Its architecture supports both single-supply (VDD = 5 V) and split-supply (±5 V) operation without performance degradation.

Input protection includes −100-mA surge current tolerance and internal ESD circuits rated to 2000 V (MIL-PRF-38535, Method 3015.2). The device features unity-gain stable compensation with 1.9 MHz gain-bandwidth product and 48° phase margin into 10 kΩ || 100 pF load.

FAQ

What is the maximum input noise voltage specification for TLC2201AID at 10 Hz?

The TLC2201AID has a maximum equivalent input noise voltage of 30 nV/√Hz at 10 Hz, as specified in the "TLC2201 AVAILABLE OPTIONS" table on page 2 of the SLOS175B datasheet. This value applies across the full industrial temperature range (−40°C to +85°C) and is a key differentiator for low-frequency sensor signal conditioning. The TLC2201AID maintains this spec under both single-supply (5 V) and split-supply (±5 V) operation.

Does TLC2201AID support rail-to-rail output swing, and what is the typical headroom?

Yes, the TLC2201AID provides rail-to-rail output swing. At 25°C with RL = 10 kΩ, the maximum positive peak output voltage is 4.7 V and the maximum negative peak is −4.7 V when powered from ±5 V supplies - indicating ≤200 mV headroom to each rail. Under single 5-V supply (VDD+ = 5 V, VDD− = GND), VOH = 4.7 V and VOL = 50 mV, confirming true rail-to-rail capability on the high side and near-rail on the low side.

What is the input bias current specification for TLC2201AID, and why does it matter in high-impedance circuits?

The TLC2201AID specifies 1 pA typical input bias current at 25°C, with a maximum of 100 pA across −40°C to +85°C. This ultra-low value is essential in high-impedance applications such as photodiode transimpedance amplifiers or piezoelectric sensor buffers, where even nanoampere-level currents would generate significant offset errors. For example, with a 1 GΩ feedback resistor, 1 pA bias introduces only 1 mV offset - preserving measurement fidelity in precision analog front-ends.

Can TLC2201AID operate from a single 5-V supply, and what are the valid input common-mode and output voltage ranges?

Yes, the TLC2201AID is fully specified for single-supply operation from 4.6 V to 16 V. With VDD = 5 V and VDD− tied to GND, the common-mode input voltage range extends from 0 V (GND) to 2.7 V, and the output swings from 50 mV (low) to 4.7 V (high) under no-load conditions. This allows direct interfacing with ground-referenced sensors and seamless driving of 12-bit ADCs with 0–5 V input ranges without level-shifting circuitry.

What is the temperature coefficient of input offset voltage for TLC2201AID, and how does it impact long-term accuracy?

The TLC2201AID has a typical temperature coefficient of input offset voltage (αVIO) of 0.5 µV/°C across its full operating range (−40°C to +85°C). This means that over a 125°C ambient swing, the offset can drift by up to ±62.5 µV - significantly less than standard precision op-amps (often >2 µV/°C). Combined with Advanced LinCMOS™ silicon-gate process stability, this enables accurate DC measurements in unregulated industrial environments without frequent recalibration.
