CSA2302MAMSOP8

The CSA2302 dual-channel high-side current-sense amplifier has precision accuracy specifications of Vos less than 10μV (typ) and gain error less than 0.1% (max). The CSA2302 features an input common-mode voltage range from 0V to 76V with 90kHz of smallsignal bandwidth, which makes it ideal for interfacing with a SAR ADC for multichannel multiplexed data acquisition systems. The CSA2302 operates over the -40°C to 125°C temperature range. The CSA2302 is offered in 8-pin MSOP package. The CSA2302 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 CSA2302 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 CSA2302 particularly useful in a wide range of high-voltage systems.
