TLC2652ACP

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2652ACP 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 maximum at 25°C and 3 µV across the full commercial temperature range (0°C to 70°C). The device operates on supply voltages from ±1.9 V to ±8 V, drawing 1.5 mA typical supply current. Key electrical parameters include a gain-bandwidth product of 1.9 MHz, a common-mode rejection ratio of 120 dB minimum, and a large-signal differential voltage amplification of 135 dB minimum. It utilizes a 14-pin plastic DIP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilization circuitry continuously nulls input offset voltage to maintain high DC precision despite variations in temperature, time, and power supply.
• Advanced LinCMOS process provides extremely high input impedance combined with low-frequency noise reduction for accurate signal processing.
• Common-mode input voltage range includes the negative rail, enabling superior performance in both single-supply and split-supply configurations.
• Integrated output clamp pin allows for exceptionally fast overload recovery times when connected.

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the component matches the specific 'C' suffix designation for the commercial temperature range of 0°C to 70°C. Confirm the 14-pin PDIP package configuration aligns with board layout requirements. Ensure external compensation capacitors are selected according to datasheet specifications for stable chopper operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this device for applications demanding ultra-low DC offset and drift rather than high-speed bandwidth. Consider the TLC2654 if higher usable bandwidth or lower noise at higher frequencies is required. Verify that the internal chopping frequency of 450 Hz does not interfere with the signal spectrum being amplified.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the TLC2652 family of precision chopper-stabilized operational amplifiers. It is distinct from the dual-channel TLC2654 and other general-purpose op-amps due to its specific focus on minimizing DC errors through continuous auto-zeroing techniques inherent to the chopper architecture.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the chopper-stabilization affect the input noise?

The chopper-stabilization technique significantly reduces low-frequency noise voltage, although it introduces a chopping frequency of 450 Hz that must be considered in filter design.

Can the TLC2652ACP operate with a single supply?

Yes, the device supports single-supply operation because the common-mode input voltage range includes the negative rail, allowing functionality even at supply levels as low as ±1.9 V.
