MAX44285 Datasheet | Maxim Integrated

Dual-Channel, High-Precision, High-Voltage, Current-Sense Amplifier General Description The MAX44285 dual-channel high-side current-sense amplifier has precision accuracy specifications of VOS less than 12μV (max) and gain error less than 0.1% (max). The MAX44285 Features an input mon-mode voltage range from 2.7V to 76V with 80k Hz 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 µMAXM packages.
