Product details
Overview
TLC2201AMFKB from Texas Instruments is a precision, low-noise single-channel 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 −55°C to 125°C. It serves in high-impedance sensor signal conditioning for military-grade data acquisition systems.
For engineers reviewing the TLC2201AMFKB datasheet, TLC2201AMFKB pinout, TLC2201AMFKB application, or TLC2201AMFKB equivalent, key selection criteria include guaranteed low-frequency noise performance, military-temperature-range operation, input bias current ≤1 pA at 25°C, common-mode range extending to the negative rail, and compatibility with both single- and split-supply configurations.
Technical Context
The TLC2201AMFKB implements a precision CMOS-input op-amp architecture with silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature and time versus metal-gate alternatives. Its input stage supports common-mode voltages down to the negative rail and withstands −100-mA surge currents without latch-up.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2), rail-to-rail output swing into 10-kΩ loads, and is fully specified for ±2.3 V to ±8 V dual-supply or 4.6 V to 16 V single-supply operation - making it suitable for low-voltage, high-fidelity analog front-ends in harsh environments.

IC Role / Device Role / Timing Role: Low-noise, high-stability gain block in multi-stage amplifiers for RF demodulation and vibration sensing subsystems. Use Value: Military-grade temp range qualification and 2000-V ESD protection eliminate derating and external protection components - reducing BOM count and board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211MDRBT | Lower noise (1.1 nV/√Hz), higher supply current (3.6 mA), SOIC-8 package | Not qualified for −55°C to +125°C; requires external ESD protection | Select when ultra-low noise dominates over temperature range and power budget permits |
| LTC2057HMS8#PBF | Zero-drift architecture, 0.5 µV max VIO, 0.005 µV/°C drift, MSOP-8 package | Higher cost; not tested for military temp range; lower slew rate (0.5 V/µs) | Select when near-zero drift is mandatory and operating range is limited to −40°C to +125°C |
Compared with OPA211MDRBT and LTC2057HMS8#PBF, the TLC2201AMFKB uniquely balances military-temperature qualification, integrated ESD robustness, and sub-30-nV/√Hz low-frequency noise - making it irreplaceable in space-constrained, high-reliability analog signal paths where external protection and thermal derating are prohibited.

FAQ
What is the maximum input noise voltage specification for the TLC2201AMFKB at 10 Hz?
The TLC2201AMFKB is B-grade tested and specified at 30 nV/√Hz maximum equivalent input noise voltage at 10 Hz. This value is confirmed in the SLOS175B datasheet, Table "TLC2201 AVAILABLE OPTIONS", and applies across the full −55°C to +125°C operating range. The typical value is 18 nV/√Hz at 25°C.
Does the TLC2201AMFKB support single-supply operation, and what is its minimum single-supply voltage?
Yes, the TLC2201AMFKB supports true single-supply operation. Its recommended operating condition specifies a single-supply range of 4.6 V to 16 V. At 4.6 V, it maintains full functionality including rail-to-rail output swing and specified input common-mode range (0 V to VDD − 2.3 V), enabling use in battery-powered and low-voltage industrial systems.
What is the input bias current specification for the TLC2201AMFKB, and how does it impact high-impedance sensor interfaces?
The TLC2201AMFKB has a typical input bias current of 1 pA at 25°C, with a maximum of 100 pA across −55°C to +125°C. This ultra-low bias current prevents loading errors in high-impedance sources such as pH electrodes (>1 GΩ), piezoresistive sensors, and photodiode transimpedance feedback networks - ensuring signal fidelity without external guarding or active bias cancellation.
Is the TLC2201AMFKB pin-compatible with other variants in the TLC220x family, such as the TLC2201B or TLC2202 series?
No - the TLC2201AMFKB uses an 8-terminal FK chip carrier package with specific bonding pad assignments (IN+, IN−, OUT, VDD−/GND, NCs), distinct from the D, P, JG, or PS packages used by other TLC220x variants. While functional behavior aligns with the TLC2201B grade (same VIO, noise, and temp range), mechanical and solder-level compatibility requires verification against each target footprint.
What packaging and assembly guidance is provided for the TLC2201AMFKB FK package?
The TLC2201AMFKB FK package is a ceramic chip carrier intended for die-level assembly. Per SLOS175B, thermal compression or ultrasonic bonding may be used on doped-aluminum bonding pads (4 × 4 mils min), and mounting options include conductive epoxy or gold-silicon preform. The backside is internally connected to Pin 4 (VDD−/GND), and the case temperature limit is 260°C for 60 seconds.
