MAX44285TAUA+

电流灵敏放大器 Dual Current-Sense with Wide Input Common Mode

Dual-Channel, High-Precision,  High-Voltage, Current-Sense Amplifier

General Description MAX44285TAUA+

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 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

wafer-level package (WLP) and 8-pin μMAXM package.
