High side current sense high voltage op amp

The CS70 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The gain is adjustable to four different values from 20 V/V up to 100 V/V by two selection pins.

Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.

The input common-mode and power-supply voltages are independent. The common-mode voltage can range from 2.9 V to 70 V in the single-supply configuration or be offset by an adjustable voltage supplied on the Vcc- pin in the dual-supply configuration.

With a current consumption lower than 360 μA and a virtually null input leakage current in standby mode, the power consumption in the applications is minimized.

Key Features

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