MAX44285:双通道,高精度,高压,电流检测放大器

集高精度与高压一体的独特组合,工作压力76V

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.
