The CS70P is a high-side current sense amplifier designed to measure small differential voltages across a shunt resistor and translate them into a ground-referenced output voltage. It supports a wide common-mode input voltage range from 2.9V up to 70V, independent of the supply voltage. The device features pin-selectable gains of 20, 25, 50, and 100 V/V, low quiescent current consumption, and high CMRR, making it suitable for industrial and automotive applications including motor control and power management.
