STMicroelectronics CS30 and CS70 Current Sense Amplifiers measure small differential voltages on high-side shunt resistors and translate them into ground referenced output voltages. The gains are internally fixed. Wide input common-mode voltage ranges, low quiescent currents, and tiny packaging enables use in a wide variety of applications. The input common-mode and power supply voltages are independent. The current consumption below 360µA (300µA CS30) and the wide supply voltage range enable the power supply to be connected to either side of the current measurement shunt with minimal error.
