MAX40201WAWA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX40201WAWA+ is a dual-channel, high-side current-sense amplifier featuring an input common-mode voltage range from 0V to 76V. It provides a fixed gain of 200V/V with a maximum input offset voltage of 33µV and a gain error of less than 0.3%. The device operates on a supply voltage between 2.7V and 5.5V, consuming approximately 2.1mA of supply current. It offers an 80kHz signal bandwidth and supports operation across a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix WAWA+ corresponds to the 200V/V gain configuration in the 8-bump wafer-level package (WLP). Confirm lead-free/RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure the ordering code matches the required temperature range and package type specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-voltage common-mode signals up to 76V require precise amplification. The 200V/V gain is suitable for applications requiring small sense voltages, such as 12.5mV full-scale. Consider the 8-bump WLP package for compact board space requirements compared to the µMAX alternative.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX40201 family of dual-channel current-sense amplifiers. It shares core specifications with variants offering different gains (25V/V, 50V/V, 100V/V) and packages (µMAX). The WAWA+ designation specifically identifies the 200V/V gain version housed in the 8-bump WLP package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes include other MAX40201 variants with different gains or packages, such as MAX40201FAWA+ (50V/V) or MAX40201WAUA+ (200V/V in µMAX). Verify pin compatibility and gain accuracy requirements when substituting.
