MAX4292EUA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4292EUA+ 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-pin µMAX package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input common-mode range extending to both supply rails

• Ultra-low quiescent supply current of 100µA per amplifier
• High precision with low input offset voltage and high open-loop gain

Instrumentation, Op Amps, Buffer Amps Applications

• Two-cell battery-operated systems
• Portable electronic equipment
• Battery-powered instrumentation
• Digital scales
• Strain gauges and sensor amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'EUA+' corresponds to the 8-pin µMAX package variant when sourcing. Confirm that the component meets the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the UCSP reliability considerations if alternative packaging is considered, as assembly methods impact mechanical integrity.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high precision in low-voltage environments where power consumption must be minimized. The rail-to-rail I/O capability allows for maximum dynamic range in single-supply systems. Consider the 500kHz bandwidth for signal conditioning tasks that do not require high-speed amplification but demand accuracy and low noise.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX429x family of micropower op amps designed for portable electronics. While the MAX4291 offers a single channel in SC70 and the MAX4294 provides four channels, the MAX4292 specifically integrates two amplifiers in the space-saving 8-bump UCSP or 8-pin µMAX packages. This configuration balances channel count with minimal footprint requirements.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4291EXK-T (single channel) and MAX4294ESD (quad channel). Verify pinout compatibility and package dimensions before substitution, as the MAX4292EUA+ utilizes the 8-pin µMAX form factor which differs from the SC70 or SO packages.
