MAX44285FAWA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX44285FAWA+T is a dual-channel, high-side current-sense amplifier featuring a gain of 50V/V. It operates with a supply voltage range of 2.7V to 5.5V and supports an input common-mode voltage from 2.7V to 76V. Key electrical specifications include a maximum input offset voltage of 12µV at +25°C and a maximum gain error of 0.1%. The device provides an 80kHz small-signal bandwidth and draws approximately 1300µA of supply current. It functions reliably across an operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FAWA' confirms the 50V/V fixed gain configuration and WLP packaging. Ensure compatibility with the required 2.7V to 5.5V supply voltage and 76V common-mode range. Confirm RoHS compliance status as indicated by the '+' designation in the ordering information before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel high-side sensing is required with a fixed gain of 50V/V. It is suitable for applications where the sense resistor voltage drop must be amplified significantly while maintaining high precision. Consider the 80kHz bandwidth and 1300µA supply current against system power and speed requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX44285 family of dual-channel, high-precision, high-voltage current-sense amplifiers. The family includes variants with different fixed gains (12.5V/V, 20V/V, 50V/V, 100V/V) and packages (WLP and µMAX). The MAX44285 series is designed for interfacing with SAR ADCs in multiplexed data acquisition systems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Other members of the MAX44285 family, such as MAX44285LAWA+T, MAX44285TAWA+T, or MAX44285HAWA+T, share identical pinouts and functionality but offer different fixed gains of 12.5V/V, 20V/V, or 100V/V respectively.
