Dual-Channel High-Precision High-Voltage Current-Sense Amplifier WS74285, VOS Less Than 70μV and Gain Error Less Than 0.1%
The WS74285 dual-channel high-side Current-Sense Amplifier has precision accuracy specifications of VOS less than 70μV (max) and gains an error of less than 0.1%(max).
The WS74285 features an input common-mode voltage range from 2.7V to 76V with 400kHz of small-signal bandwidth, which makes it ideal for interfacing with a SARADC for multichannel multiplexed data acquisition systems.
The WS74285 operates over the -40℃ to +125℃ temperature range. The WS74285 is offered in an 8-pin MSOP and CSP package.
