Product details
Overview
TLC2252MUB from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier designed for precision signal conditioning in low-voltage, battery-powered systems. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and rail-to-rail output swing - enabling full dynamic range utilization with single- or split-supply operation down to ±2.2 V. It is used in high-impedance sensor interfaces such as piezoelectric transducers and remote analog front-ends.
For engineers reviewing the TLC2252MUB datasheet, TLC2252MUB pinout, TLC2252MUB application, or TLC2252MUB equivalent, key selection criteria include its –55°C to 125°C operating temperature range, 850 µV max input offset voltage (TLC2252AM variant), low-noise performance, and compatibility with ADC driving and single-supply instrumentation circuits.
Technical Context
The TLC2252MUB implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low input offset voltage drift (0.5 µV/°C). Its input stage operates with common-mode voltage extending to the negative rail, supporting true single-supply operation without level-shifting circuitry.
This device features fully characterized performance across ±2.2 V to ±8 V supply ranges and supports stable unity-gain operation with 63° phase margin and 15 dB gain margin into 50 kΩ || 100 pF loads - making it suitable for low-frequency precision amplification without external compensation.

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 |
|---|---|---|---|
| TLV2432IDR | Higher supply current (600 µA/ch), wider GBW (2.2 MHz), but only rated to 125°C (not –55°C) | Not suitable for extended cold-temperature operation or space-grade designs | Select when higher speed and drive capability outweigh ultra-low power and extreme temperature needs |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C VIO drift, but 17 µA/ch supply current and no –55°C rating | Lacks military-grade temperature range; optimized for DC precision, not wide-temp robustness | Prefer for ultra-stable DC offsets in medical instruments where temperature extremes are not present |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2252MUB uniquely balances micropower operation (35 µA/ch), rail-to-rail output, and –55°C to 125°C qualification - making it irreplaceable in battery-powered, wide-temperature, high-reliability analog signal chains where long-term stability and supply headroom are constrained.

FAQ
What is the maximum operating supply voltage for the TLC2252MUB?
The TLC2252MUB supports a maximum supply voltage of ±8 V across VDD+ and VDD– terminals. Absolute maximum ratings specify ±8 V for each supply rail, with differential input voltage limited to ±16 V. Operation within ±2.2 V to ±8 V is fully characterized per the datasheet, and exceeding ±8 V risks permanent device damage.
Does the TLC2252MUB support true single-supply operation with input signals referenced to ground?
Yes, the TLC2252MUB supports true single-supply operation: its common-mode input voltage range extends to the negative rail (VDD– or GND), and the output swings rail-to-rail. When powered from a single 5 V supply (VDD+ = 5 V, VDD– = GND), inputs can be applied from 0 V to 3.5 V, and outputs deliver 0 V to 5 V - eliminating the need for input biasing or level-shifting circuitry in the TLC2252MUB design.
What is the guaranteed input offset voltage specification for the TLC2252MUB across temperature?
The TLC2252MUB is part of the TLC2252AM variant, which guarantees a maximum input offset voltage of 850 µV at TA = 25°C and 1000 µV over the full –55°C to 125°C operating range. The temperature coefficient is specified at 0.5 µV/°C, meaning worst-case drift contributes ≤130 µV over a 260°C span - well within the 1000 µV full-range limit confirmed in the datasheet's electrical characteristics table.
Is the TLC2252MUB pin-compatible with earlier TLC27L2 or TS27L2 devices?
No, the TLC2252MUB is not pin-compatible with TLC27L2 or TS27L2. While it serves as a functional upgrade offering lower noise, rail-to-rail output, and improved input offset, the TLC2252MUB uses an 8-pin ceramic DIP (JG) package with different internal routing and biasing. Pin mapping differs - notably, the TLC2252MUB places both amplifier outputs on pins 1 and 8, whereas TLC27L2 uses pins 1 and 7 - requiring PCB layout revision for replacement.
What packaging and screening level does the 'M' suffix indicate in TLC2252MUB?
The 'M' suffix in TLC2252MUB denotes compliance with MIL-PRF-38535 Class K requirements, including extended temperature operation from –55°C to 125°C, hermetic ceramic DIP (JG) packaging, and full characterization across that range. The 'U' indicates the JG package variant, and 'B' is a date/batch code - confirming this is a high-reliability, space-qualified dual op-amp intended for defense and aerospace applications.
