Description
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 singlesupply configuration or be offset by an adjustable voltage supplied on the Vcc- pin in the dualsupply 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. 2 1 3 SEL2 Vm SEL1 6 8 Gnd Vp 4 Out 7 Vcc5 Vcc+ TSSOP8 (Plastic package)
