Product details
Overview
TLC2201ID from Texas Instruments is a precision, low-noise rail-to-rail output operational amplifier using Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max input noise at 10 Hz, and 12 nV/√Hz max at 1 kHz across −40°C to +85°C, enabling high-impedance sensor signal conditioning in single- or split-supply industrial data acquisition systems.
For engineers reviewing the TLC2201ID datasheet, TLC2201ID pinout, TLC2201ID application, or TLC2201ID equivalent, key selection criteria include its guaranteed low-noise performance over temperature, rail-to-rail output swing with negative-rail-inclusive common-mode input range, and ±2.3 V to ±8 V dual-supply operation - critical for precision analog front-ends in medical instrumentation and test equipment.
Technical Context
The TLC2201ID implements a silicon-gate Advanced LinCMOS™ architecture that achieves superior input offset voltage stability over time and temperature versus metal-gate JFET amplifiers. Its input stage includes high-impedance p-channel MOSFETs delivering 1 pA typical input bias current at 25°C.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2) and robust input/output surge tolerance (−100 mA), supporting reliable operation in noisy industrial environments without latch-up under transient stress.

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 0.1 µV/°C max drift, bipolar input (2 nA IB), higher 2.8 µV VIO max - better DC stability but higher noise (10 nV/√Hz @ 1 kHz) | Preferred in ultra-stable DC-coupled integrators and zero-drift metrology systems where noise >100 Hz is secondary | Select OPA2277UA when long-term offset drift dominates system error budget over broadband noise |
| AD8628ARZ | Zero-drift chopper architecture, 1 µV VIO max, 0.005 µV/°C drift, but 60 nV/√Hz 1/f noise peak - superior DC specs, worse low-frequency noise | Suitable for DC-coupled load cell amplifiers where 0.1–10 Hz noise is filtered, but not for seismic or bio-potential sensing | Choose AD8628ARZ for applications demanding sub-microvolt offset stability with post-filtering of chopper ripple |
Compared with OPA2277UA and AD8628ARZ, the TLC2201ID provides optimal balance of low 1/f noise, rail-to-rail output, and industrial temperature range - making it uniquely suited for unfiltered low-frequency sensor interfaces where both noise and drift matter.

FAQ
What is the maximum supply voltage rating for the TLC2201ID?
The TLC2201ID has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD− terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.3 V to ±8 V, with thermal derating applied above 25°C ambient per the dissipation rating table in the datasheet. The TLC2201ID must never be subjected to differential supply voltages exceeding 16 V.
Does the TLC2201ID support true rail-to-rail input operation?
No, the TLC2201ID does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 2.3 V under recommended conditions. This means it accepts inputs down to ground in single-supply use but cannot handle signals at the positive rail. The TLC2201ID's key strength is rail-to-rail *output* swing - delivering ±4.7 V minimum at ±5 V supplies - not full rail-to-rail input capability.
How does the noise performance of the TLC2201ID compare between the B-grade and standard grade versions?
The TLC2201ID is the I-suffix (−40°C to +85°C) version of the B-grade device. Per the datasheet, TLC2201B variants are 100% tested for noise: 30 nV/√Hz max at 10 Hz and 12 nV/√Hz max at 1 kHz. Standard-grade (non-B) versions like TLC2201ID (without 'B') have relaxed noise specs - 35 nV/√Hz max at 10 Hz and 15 nV/√Hz max at 1 kHz. Thus, TLC2201ID meets B-grade noise only if marked 'TLC2201BID'; the base TLC2201ID part uses standard-grade noise limits.
Can the TLC2201ID drive capacitive loads without instability?
The TLC2201ID is unity-gain stable with capacitive loads up to 100 pF when driving a 10 kΩ resistive load, as verified by phase margin testing (48° at unity gain). For loads exceeding 100 pF - such as ADC input capacitors or long cables - external isolation resistance (e.g., 100 Ω in series with the output) is required to maintain stability. Driving purely capacitive loads >500 pF is not recommended without compensation networks per Figure 9 in the datasheet.
Is the TLC2201ID pin-compatible with other devices in the TLC220x family?
Yes, all TLC220x devices in the SOIC-8 (D) package - including TLC2201ID, TLC2201CD, TLC2201AID, and TLC2202ID - share identical pinouts and footprint. However, electrical differences exist: TLC2202ID is a dual-channel variant, while TLC2201ID is single-channel; B-grade parts offer tighter noise specs; and suffixes denote temperature grade (I = −40°C to +85°C). PCB layout may be reused, but schematic review is essential to confirm channel count and performance alignment for the target application.
