Product details
Overview
TLC2262MJG from Texas Instruments is a dual rail-to-rail output operational amplifier in ceramic DIP (JG) package, rated for –55°C to 125°C operation. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current per amplifier, and rail-to-rail output swing-enabling high-precision signal conditioning in aerospace sensor interfaces and military-grade data acquisition systems.
For engineers reviewing the TLC2262MJG datasheet, TLC2262MJG pinout, TLC2262MJG application, or TLC2262MJG equivalent, this device is selected for low-noise, high-impedance analog front-ends where extended temperature range, CMOS input stage stability, and single/dual-supply flexibility are critical design requirements.
Technical Context
The TLC2262MJG uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise (12 nV/√Hz @ 1 kHz). Its input common-mode range extends to the negative rail, supporting true single-supply operation down to ±2.2 V.
It features fully characterized performance across –55°C to 125°C, with guaranteed 950 µV max input offset voltage for the 'A' variant (TLC2262AMJG), though the base TLC2262MJG specifies 2.5 mV max at 25°C. The device is qualified to MIL-PRF-38535 standards and supports Q-Temp automotive high-reliability applications.

FAQ
What is the maximum supply voltage rating for the TLC2262MJG?
The TLC2262MJG has an absolute maximum supply voltage of ±8 V (or 16 V total across VDD+ and VDD–). Operation beyond this risks permanent damage. Recommended operating range is ±2.2 V to ±8 V for split supply or +4.4 V to +16 V for single supply, with full electrical specifications guaranteed across that span.
Does the TLC2262MJG support true single-supply operation with input signals near ground?
Yes. The TLC2262MJG's common-mode input voltage range includes the negative rail (VDD–/GND), allowing inputs down to 0 V in single-supply configurations. This enables direct interfacing with ground-referenced sensors such as strain gauges or current shunts without level-shifting circuitry.
Is the TLC2262MJG pin-compatible with earlier TLC27M2 or TS27M2 devices?
Yes-the TLC2262MJG uses the same 8-pin DIP (JG) pinout as the TLC27M2 and TS27M2. It serves as a direct functional upgrade, offering rail-to-rail output, lower noise (12 nV/√Hz vs. ~25 nV/√Hz), lower input offset voltage, and improved input bias current-without requiring PCB layout changes.
What is the guaranteed input offset voltage specification for the TLC2262MJG at 25°C?
The TLC2262MJG guarantees a maximum input offset voltage of 2.5 mV at 25°C. For tighter DC precision, the pin-compatible TLC2262AMJG variant is available with 950 µV max VIO at 25°C and is also rated for –55°C to 125°C operation.
Can the TLC2262MJG drive capacitive loads up to 100 pF without instability?
Yes. The TLC2262MJG is characterized with 100 pF capacitive load and exhibits 56° phase margin at unity gain with 50 kΩ load, ensuring stable operation in typical ADC driver and filter applications. Layout best practices (short traces, local bypassing) are still recommended for optimal high-frequency performance.
