TLC2652I-8D

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2652I-8D is a precision chopper-stabilized operational amplifier manufactured by Texas Instruments using Advanced LinCMOS technology. It features an input offset voltage of 1 µV max at 25°C and 2.95 µV across the full temperature range. The device operates with supply voltages from ±1.9 V to ±8 V, drawing 1.5 mA typical current. Key electrical parameters include a gain-bandwidth product of 1.9 MHz, negative slew rate of 3.1 V/µs, and common-mode rejection ratio of 120 dB min. It is characterized for operation from -40°C to 85°C in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the I-suffix indicates the -40°C to 85°C operating range. Confirm the D suffix corresponds to the 8-pin Small Outline package. Ensure external capacitors are included for chopper stabilization as required by the datasheet specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring ultra-low offset voltage and drift without external trimming. Consider the TLC2654 if higher bandwidth or lower noise is needed. Verify that the internal chopping frequency of 450 Hz does not interfere with the signal spectrum.
