TLC2652AI-8D

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2652AI-8D is a single-channel, 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 industrial temperature range (-40°C to 85°C). The device operates on supply voltages from ±1.9 V to ±8 V with a typical supply current of 1.5 mA. Key electrical parameters include a gain-bandwidth product of 1.9 MHz, negative slew rate of 3.1 V/µs, common-mode rejection ratio of 120 dB min, and supply-voltage rejection ratio of 110 dB min.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilization circuitry continuously nulls input offset voltage to maintain high DC precision across temperature and time variations.
• Advanced LinCMOS process provides extremely high input impedance combined with low input bias current.
• Common-mode input voltage range includes the negative rail, enabling superior performance in single-supply or split-supply configurations.
• Internal clamp circuit reduces overload recovery time, while robust input stages withstand surge currents without latch-up.

Instrumentation, Op Amps, Buffer Amps Applications

• Strain gauge signal conditioning
• Thermocouple amplification
• Low-level transducer signal processing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'I' confirms the -40°C to 85°C operating temperature range and '8D' indicates the 8-pin SOIC package. Confirm RoHS compliance status as required for your assembly process. Ensure external capacitors are connected to the CXA and CXB pins for proper chopper stabilization operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low DC offset and drift are critical requirements. The I-suffix variant is appropriate for industrial environments requiring extended temperature coverage compared to the C-suffix. Consider the TLC2654 if higher bandwidth or lower noise density is needed, as it utilizes a different chopping frequency.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLC2652 family of precision chopper-stabilized amplifiers. It is part of Texas Instruments' portfolio designed for applications demanding high accuracy without the need for external trimming. The AI-8D designation specifically denotes the industrial temperature grade within the small outline package format.
