Description

The CS30 measures a small differential voltage

on a high-side shunt resistor and translates it into

a ground referenced output voltage. The gain is

internally fixed.

Wide input common-mode voltage range, low

quiescent current, and tiny SOT23 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 2.8 to 30 V in operating

conditions and up to 60 V in absolute maximum

rating conditions.

The current consumption below 300 µA and the

wide supply voltage range enable the power

supply to be connected to either side of the

current measurement shunt with minimal error.
