MAX40201EVKIT#: Amplifier IC Development Tools EVKit for MAX40201 Dual 0V to76V Current Sense Amplifiers

 

Features, Applications

The MAX40201 dual-channel, high-side, current-sense amplifier has VOS of less than 12V (max) and gain error of less than 0.1% (max). The outputs of the MAX40201 are voltage outputs capable of swinging to a few tens of millivolts of the VDD rail and ground. The MAX40201 features an input common-mode voltage range from 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 MAX40201 operates over the to +125C temperature range. The MAX40201 is offered in 8-bump wafer-level package (WLP) and 8-pin MAX package.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
