Product details
Overview
TLC2201MFKB from Texas Instruments is a precision, low-noise, single-channel operational amplifier using 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 across −55°C to 125°C. It serves as a high-impedance signal-conditioning amplifier in military-grade sensor front-ends and precision data acquisition systems.
For engineers reviewing the TLC2201MFKB datasheet, TLC2201MFKB pinout, TLC2201MFKB application, or TLC2201MFKB equivalent, key selection criteria include its military-temperature-rated noise performance, input bias current of 1 pA typ, common-mode input range extending to the negative rail, and compatibility with both single-supply (up to 16 V) and split-supply (±8 V) configurations.
Technical Context
The TLC2201MFKB implements a precision JFET-input architecture with silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature (0.5 µV/°C typ) and time versus metal-gate alternatives. Its input stage includes ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2) and tolerance for −100-mA surge currents without latch-up.
It features fully specified operation from ±2.3 V to ±8 V dual supply or 4.6 V to 16 V single supply, with rail-to-rail output swing delivering ≥4.7 V peak positive and ≤−4.7 V peak negative swing into 10-kΩ load at ±5 V supply. Common-mode input voltage range spans from VDD− to (VDD+ − 2.3 V), including the negative rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max - enables sub-mV DC accuracy in high-gain sensor amplification stages without trimming. |
| Input Noise Voltage | 30 nV/√Hz max at 10 Hz - supports low-frequency precision measurement in strain gauges and thermopiles. |
| Input Bias Current | 1 pA typ at 25°C - preserves signal integrity in ultra-high-impedance pH electrodes and photodiode transimpedance circuits. |
| Supply Voltage Range | ±2.3 V to ±8 V (dual) or 4.6 V to 16 V (single) - allows flexible integration into legacy ±5 V, ±15 V, or modern 3.3 V/5 V/12 V systems. |
| Operating Temperature | −55°C to +125°C - qualified for aerospace, downhole, and engine-control applications requiring full military-grade thermal robustness. |
| Rail-to-Rail Output | Swings within 300 mV of rails into 10-kΩ load - maximizes dynamic range in single-supply data loggers and battery-powered instrumentation. |
| Common-Mode Input Range | Includes VDD− - permits direct sensing of signals referenced to ground in single-supply configurations without level-shifting. |
Pinout & Package
Package: FK (Chip Carrier, ceramic, 8-terminal, unsealed, leadless). Dimensions per datasheet: 4.9 × 4.9 mm body, 15 mil chip thickness, 4 × 4 mil bonding pads. Rated for 260°C reflow (60 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD+ | Positive Supply | Accepts up to +8 V in dual supply or up to +16 V in single supply; decoupling required within 1 cm. |
| VDD−/GND | Negative Supply / Ground Reference | Serves as return path; common-mode input extends to this pin - critical for true single-supply operation. |
| IN+ | Non-Inverting Input | Ultra-high-impedance node (≥1012 Ω); sensitive to PCB leakage and guarding layout. |
| IN− | Inverting Input | High-impedance feedback node; requires symmetric trace routing to minimize offset drift. |
| OUT | Amplifier Output | Capable of ±50 mA short-circuit current; stable driving 100-pF capacitive loads per phase margin spec. |
| NC | No Internal Connection | Three pins (1, 2, 7) are unconnected - must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low 1/f Noise | 30 nV/√Hz max at 10 Hz - reduces drift and error in DC-coupled medical ECG and industrial weigh-scale amplifiers. |
| Advanced LinCMOS™ Process | Input offset voltage drift <0.5 µV/°C - eliminates need for external nulling in field-deployed environmental monitoring nodes. |
| Rail-to-Rail Output | Delivers >94% of full supply swing - increases usable ADC input range in 16-bit SAR-based data acquisition modules. |
| Military Temperature Rating | Qualified from −55°C to +125°C - meets MIL-STD-883 screening requirements for Class B devices without derating. |
| ESD Protection | 2000 V HBM per MIL-PRF-38535 - reduces handling sensitivity during board assembly and field maintenance. |
Applications
| Strain Gauge Signal Conditioning | Thermocouple Cold-Junction Compensation |
|---|---|
Use Scenario: Amplifying microvolt-level Wheatstone bridge outputs in structural health monitoring sensors exposed to wide ambient temperature swings. IC Role / Device Role: Precision instrumentation amplifier front-end with gain ≥1000 and DC-coupled offset rejection. Use Value: 500 µV max VIO and 0.5 µV/°C drift ensure <1 LSB error over temperature in 16-bit systems without calibration. | Use Scenario: Buffering and cold-junction compensation voltage from thermistor networks in industrial furnace controllers. IC Role / Device Role: Low-drift, low-noise unity-gain buffer isolating thermistor from ADC input loading.

IC Role / Device Role: First-stage gain and filtering amplifier in fault-tolerant analog front-end with extended temperature survival. Use Value: −55°C to +125°C rating ensures functionality during orbital thermal cycling; 30 nV/√Hz noise preserves SNR in low-g vibration detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211MDRGTEP | Lower noise (1.1 nV/√Hz), higher supply current (3.6 mA), SOIC-8 package only | Not qualified for −55°C; limited to −55°C to +125°C only in specific EP variant - not identical temp range coverage | Select when ultra-low noise dominates over power and military temp compliance is secondary. |
| LTC2057HMS8#PBF | Zero-drift architecture, 0.5 µV max VIO, but higher 1/f noise corner (~10 Hz) and no military temp grade | Specified only to +125°C (not −55°C); lacks rail-to-rail output - limits single-supply headroom | Prefer for zero-drift DC stability where low-frequency noise is less critical than absolute offset. |
Compared with OPA211MDRGTEP and LTC2057HMS8#PBF, the TLC2201MFKB uniquely combines military-temperature qualification, JFET-input ultra-low bias current, and validated 30-nV/√Hz noise at 10 Hz - making it irreplaceable in high-reliability, low-power, wide-temperature analog signal chains where zero-drift isn't mandatory.

FAQ
What is the maximum supply voltage for TLC2201MFKB in single-supply operation?
The TLC2201MFKB supports single-supply operation from 4.6 V to 16 V. At 16 V, it maintains full specification compliance including input offset voltage, noise, and output swing - verified across the full −55°C to +125°C temperature range per the SLOS175B datasheet Absolute Maximum Ratings table.
Does TLC2201MFKB support true rail-to-rail input?
No, the TLC2201MFKB does not support rail-to-rail input. Its common-mode input voltage range extends from VDD− to (VDD+ − 2.3 V), meaning the positive input cannot reach within 2.3 V of VDD+. However, it does include the negative rail - enabling ground-referenced inputs in single-supply use cases.
How is the "M" suffix reflected in the TLC2201MFKB's specifications?
The "M" suffix in TLC2201MFKB denotes full military temperature qualification (−55°C to +125°C), distinct from commercial (C) or industrial (I) grades. All electrical parameters - including input offset voltage (500 µV max), noise (30 nV/√Hz at 10 Hz), and supply current (1.5 mA max) - are guaranteed across this extended range, not just at 25°C.
Can TLC2201MFKB drive capacitive loads without instability?
Yes, the TLC2201MFKB is characterized for stability with 100-pF capacitive loads at unity gain (phase margin = 48° at 25°C). For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain phase margin above 45° across temperature.
What packaging format does the "FK" in TLC2201MFKB indicate?
The "FK" suffix identifies the ceramic chip carrier package: 8-terminal, unsealed, leadless, with 4.9 × 4.9 mm footprint and gold-plated bonding pads. It is designed for hybrid microcircuit assembly using conductive epoxy or gold-silicon eutectic die attach, and rated for 260°C reflow (60 s).
