STMicroelectronics CSx0 Current Sense Amplifiers

ST CS30, CS70 Current Sense Amplifiers

STMicroelectronics CS30, 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.


CS70 Features
  • Independent supply and input common-mode voltages
  • Wide common-mode operating range: 2.9V to 70 V in single-supply configuration, -2.1V to 65V in dual-supply configuration
  • Wide common-mode surviving range: -16V to 75V (reversed battery and load-dump conditions)
  • Supply voltage range: 2.7 to 5.5V in single supply configuration
  • Low current consumption: ICC max = 360µA
  • Pin selectable gain: 20 V/V, 25 V/V, 50 V/V or 100 V/V
  • Buffered output
