The from Texas Instruments is a INA303 high speed precision current sense amplifier evaluation module. The INA303 is a voltage output current shunt monitor with integrated dual high speed comparators that enable accurate current measurement in conjunction with fast over and undercurrent detection capability. Dual comparators of INA303 function as a window comparator, enabling users to detect over and undercurrent events. The INA303EVM evaluates main features and performance of INA303 high speed precision current sense amplifier with dual integrated comparators, across its specified input voltage, common mode voltage and temperature ranges. The module is a PCB consisting of three independent break away sections. Each section contains a different variant of the corresponding device, along with its own set of input, output and power terminals, as well as signal and power conditioning circuitry to allow users to test each device variant independently.
