说明

The MAX44285 dual-channel high-side current-sense amplifier has precision accuracy specifications of VOS less than 10µV (max) and gain error less than 0.1% (max).

The MAX44285 features an input common-mode voltage range from 2.7V to 76V with 80kHz of small-signal bandwidth, which makes it ideal for interfacing with a SAR ADC for multichannel multiplexed data acquisition systems.

The MAX44285 operates over the -40°C to +125°C temperature range. The MAX44285 is offered in 8-bump WLP and 8-pin µMAX® packages.
