Part Number:MAXREFDES77
The MAXREFDES77# peripheral module provides the necessary hardware to interface the MAX44285 dual-channel high-side current-sense amplifier device to any system that utilizes Pmod™-compatible expansion ports configurable for SPI communication. The IC features an input common-mode voltage range from 2.7V to 76V with 80kHz small-signal bandwidth, making it ideal for interfacing with a SAR ADC for multichannel, multiplexed data acquisition systems.

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.
