MAX4292EUA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4292EUA+T is a dual-channel micropower operational amplifier from the MAX4291/MAX4292/MAX4294 family. It operates on a single supply of 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V, consuming only 100µA per amplifier. Key electrical parameters include a 500kHz gain-bandwidth product, 120dB open-loop voltage gain, and a typical input offset voltage of ±200µV. The device features rail-to-rail input and output capabilities, with outputs swinging to within 46mV of the rails under a 2kΩ load. It is housed in an 8-bump UCSP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'E' designation corresponds to the -40°C to +85°C industrial temperature range. Ensure compatibility with the 8-bump UCSP footprint during PCB layout. Check for RoHS compliance status as indicated in official documentation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside precision signal conditioning. The dual-channel configuration saves board space compared to single-channel alternatives. Consider the UCSP package constraints regarding mechanical reliability and assembly methods. Evaluate the 500kHz bandwidth against signal frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX429x family of ultra-small, micropower op amps. While the MAX4291 offers a single channel in SC70 and the MAX4294 provides four channels, the MAX4292 specifically delivers two channels in the compact UCSP format. This family targets low-voltage, battery-powered portable electronics where size and current efficiency are critical design factors.
