OPA2202IDGKT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2202IDGKT is a dual precision operational amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It features a low input offset voltage of 20 µV and a low noise density of 9 nV/√Hz. The device operates with a supply voltage range from 4.5 V to 36 V and delivers a high output current of 35 mA per channel. With a gain-bandwidth product of 1 MHz and a slew rate of 350 mV/µs, it supports operation across a temperature range of -40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDGKT corresponds to the VSSOP-8 tape and reel packaging configuration. Confirm that the operating temperature range extends to 125°C as specified for this variant. Ensure compatibility with standard surface-mount reflow profiles for thin-shrink small-outline packages during assembly planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both low offset voltage and low noise are critical requirements simultaneously. The dual-channel architecture reduces board space compared to single-channel alternatives. Consider the 35 mA output current for driving moderate loads directly without additional buffering stages.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx202 family of precision amplifiers designed for applications requiring superior DC performance. The OPA2202 specifically targets dual-channel implementations where size constraints favor the VSSOP package over larger SOIC or DIP options while maintaining high precision specifications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Official substitutes within the same family include the OPA2202IDRG4 for reel-packaged versions. Designers should verify pinout compatibility and thermal characteristics when transitioning between different package variants of the OPAx202 series.
