TLC2652MJG

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2652MJG is a high-precision, single-channel chopper-stabilized operational amplifier manufactured by Texas Instruments using the Advanced LinCMOS process. It features an extremely low input offset voltage of 3 µV maximum and a temperature coefficient of 0.003 µV/°C typical. The device operates over a military temperature range of -55°C to 125°C with supply voltages from ±1.9 V to ±8 V. Key electrical characteristics include a minimum large-signal differential voltage gain of 120 dB, a common-mode rejection ratio of 120 dB, and a supply-voltage rejection ratio of 110 dB. It utilizes an internal chopping frequency of 450 Hz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilization circuitry continuously nulls input offset voltage across temperature, time, and supply variations.
• Advanced LinCMOS technology provides extremely high input impedance and low bias current.
• Single-supply operation capability with common-mode input voltage range including the negative rail.
• Integrated output clamp pin for reduced overload recovery time.

Instrumentation, Op Amps, Buffer Amps Applications

• Strain gauge signal processing
• Thermocouple amplification
• Transducer amplifiers requiring low-level signal conditioning

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the M suffix indicates full military temperature characterization (-55°C to 125°C). Confirm the JG package designation corresponds to the 8-pin ceramic DIP format. Ensure compliance with MIL-PRF-38535 if specific military qualification is required, noting that some parameters may not be production tested on compliant products.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications demanding ultra-low DC offset and drift without external trimming. The M suffix is necessary for environments exceeding standard industrial temperature limits. Consider the TLC2654A if higher bandwidth or lower noise at higher frequencies is required, as it operates at a 10 kHz chopping frequency.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLC2652 family of precision chopper-stabilized amplifiers. The MJG variant specifically denotes the military-grade temperature range and ceramic dual in-line package construction. It shares functional similarities with the TLC2652M but is distinguished by its packaging and potential qualification standards.
