MAX4402AUA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4402AUA/V+T is a dual-channel, low-cost operational amplifier from the MAX4400–MAX4403 series. It operates on a single +2.5V to +5.5V supply and draws 320µA of quiescent current per amplifier. The device features rail-to-rail outputs, delivering ±1.4mA of output current, and maintains unity-gain stability with capacitive loads up to 400pF. It includes ground-sensing inputs and an 800kHz gain-bandwidth product. The component is specified for operation across a temperature range of -40°C to +125°C and is available in an 8-pin µMAX package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix '/V+' indicates AEC-Q100 automotive qualification status as documented in the official datasheet selector guide. Confirm the 'T' designation corresponds to tape-and-reel packaging if required by assembly processes. Ensure the µMAX package variant matches the intended footprint constraints. Cross-reference the full part number against manufacturer documentation to validate all electrical specifications and environmental ratings prior to procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel general-purpose amplifier with rail-to-rail output is required within a compact µMAX footprint. It is suitable for applications demanding low power consumption and operation from a single +2.5V to +5.5V supply. Consider this part for harsh environments requiring extended temperature ranges up to +125°C. Verify that the 800kHz bandwidth and 1.4mA output current meet the specific circuit requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4402AUA/V+T belongs to the MAX4400–MAX4403 family of low-cost, single-supply operational amplifiers. This series offers rail-to-rail outputs and low quiescent current. While the MAX4400 is a single amplifier, the MAX4402 provides two channels in an 8-pin package. The MAX4401 adds a shutdown feature, and the MAX4403 offers four channels. All variants share similar core electrical characteristics and are designed for portable and automotive applications.
