TION KIT EVALUA BLE AVAILA
High-Side, Current-Sense Amplifiers with 12-Bit ADC and Op Amp/Comparator
General Description
The MAX9611/MAX9612 are high-side current-sense amplifiers with an integrated 12-bit ADC and a gain block that can be configured either as an op amp or comparator, making these devices ideal for a number of industrial and automotive applications.

The high-side, current-sense amplifiers operate over a wide 0V to 60V input common-mode voltage range. The programmable full-scale voltage (440mV, 110mV, and 55mV) of these amplifiers offers wide dynamic range, accurate current measurement, and application flexibility in choosing sense resistor values. A choice of either an internal op amp or a comparator is provided to the user. The internal amplifier can be used to limit the inrush current or to create a current source in a closed-loop system. The comparator can be used to monitor fault events for fast response. An I2C controlled 12-bit, 500sps analo
