Product details
Overview
TLC2252MFKB from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in a ceramic chip carrier (FK) package, rated for –55°C to 125°C operation. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 1 pA typical input bias current, enabling precision signal conditioning in battery-powered aerospace and military systems where wide temperature range and micropower operation are critical.
For engineers reviewing the TLC2252MFKB datasheet, TLC2252MFKB pinout, TLC2252MFKB application, or TLC2252MFKB equivalent, this device is selected for ultra-low-power analog front-ends requiring rail-to-rail output swing, high input impedance, and stable performance across extreme temperatures - especially in piezoelectric sensor interfaces, remote telemetry nodes, and radiation-tolerant instrumentation.
Technical Context
The TLC2252MFKB uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low noise (19 nV/√Hz). Its input common-mode range extends to the negative rail, supporting single-supply operation down to ±2.2 V.
It features fully characterized performance over –55°C to 125°C, with maximum input offset voltage of 1500 µV (M-grade), 70 dB minimum CMRR, and 80 dB minimum PSRR - optimized for high-impedance source amplification and ADC driver applications in harsh environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333MDRGTEP | Chopper-stabilized (0.02 µV/°C drift), 17 µA/ch, 5.5 µV max VIO - lower offset but higher quiescent current than TLC2252MFKB | Better for DC-critical applications (e.g., precision weigh scales); less suitable for ultra-low-power wake-up circuits | Select OPA2333MDRGTEP when long-term DC stability outweighs battery life; TLC2252MFKB remains preferred for <50 µA system budgets |
| LMC6062IMX/NOPB | CMOS input (2 fA IB), 100 µA/ch, 1.5 mV max VIO - higher power, lower noise floor (12 nV/√Hz), wider GBW (1.4 MHz) | Better for higher-speed sensor interfaces (>100 kHz) where noise dominates over power | Choose LMC6062IMX/NOPB when bandwidth >100 kHz is required; TLC2252MFKB excels where sub-50 µA/ch and extreme temp range are non-negotiable |
Compared with OPA2333MDRGTEP and LMC6062IMX/NOPB, the TLC2252MFKB uniquely balances ultra-low power (35 µA/ch), extended temperature range (–55°C to 125°C), and hermetic ceramic packaging - making it irreplaceable in legacy aerospace designs and new high-reliability programs where qualification pedigree and radiation tolerance are mandatory.

FAQ
What is the maximum operating temperature range for the TLC2252MFKB?
The TLC2252MFKB is rated for continuous operation from –55°C to 125°C, meeting MIL-PRF-38535 Class B requirements. This range is validated across all electrical parameters including input offset voltage (1500 µV max), supply current (≤150 µA total), and output drive capability - making it suitable for engine bay, space, and downhole electronics where thermal extremes are routine.
Does the TLC2252MFKB support single-supply operation?
Yes, the TLC2252MFKB fully supports single-supply operation from +4.4 V to +16 V, with input common-mode voltage range extending to the negative rail (GND) and rail-to-rail output swing. When operated from a 5-V single supply, its inputs accept 0 V to 3.5 V, and outputs swing within 10 mV of 0 V and 5 V - ideal for interfacing with 3.3-V or 5-V ADCs without level-shifting circuitry.
What is the input offset voltage specification for TLC2252MFKB over temperature?
The TLC2252MFKB has a maximum input offset voltage of 1500 µV over its full operating range of –55°C to 125°C. At 25°C, typical VIO is 200 µV with a maximum of 1500 µV. Its temperature coefficient is 0.5 µV/°C, meaning worst-case drift adds ≤75 µV over a 150°C span - a key parameter for DC-coupled sensor amplifiers where calibration stability matters.
How does the noise performance of TLC2252MFKB compare to earlier LinCMOS amplifiers?
The TLC2252MFKB delivers 19 nV/√Hz input voltage noise at 1 kHz - four times lower than predecessors like the TLC27L2. This improvement stems from optimized transistor sizing and biasing in the Advanced LinCMOS™ process. At 10 Hz, noise is 36 nV/√Hz, confirming low 1/f noise corner - critical for precision DC-to-100-Hz sensor applications such as seismic monitoring and medical biosensors.
Is the TLC2252MFKB pin-compatible with the TLC2252MJG or TLC2252MU packages?
No, the TLC2252MFKB (14-pin ceramic chip carrier) is not pin-compatible with the TLC2252MJG (14-pin ceramic DIP) or TLC2252MU (14-pin ceramic flatpack). While all three share identical electrical functionality and pin function definitions, their physical layouts differ: FK uses perimeter terminations with center pad grounding, JG uses through-hole leads, and U uses gull-wing leads. PCB layout must be redesigned for each package type.
