CSA231MASOIC8

The CSA231 bidirectional high-side current-sense amplifier has precision accuracy specifications of Vos less than 10μν (typ) and gain error less than 0.1% (max). The CSA231 features an input common-mode voltage range from 0V to 76V with 90kHz of small - signal bandwidth, which makes it ideal for interfacing with an ADC for multichannel multiplexed data acquisition systems. The CSA231 operates over the - 40°C to 125°C temperature range. The CSA231 high - side, current - sense amplifier features a 0V to 76V input common - mode range that is independent of supply voltage. This feature allows the monitoring of current out of a battery as low as 0V and enables high - side current sensing at voltages greater than the supply voltage (VDD). The CSA231 monitors current through a current - sense resistor and amplifies the voltage across the resistor. High - side current monitoring does not interfere with the ground path of the load being measured, making the CSA231 particularly useful in a wide range of high - voltage systems.
