CSA220MASOT235

The CSA220 high-side current-sense amplifier has precision accuracy specifications of Vos less than 60μν (max) and gain error less than 0.1% (max). The CSA220 features an input common-mode voltage range from 0V to 76V with 50kHz of small - signal bandwidth, which makes it ideal for interfacing with an ADC for multichannel multiplexed data acquisition systems. Low power consumption and small package make the CSA220 ideal for portable devices. The CSA220 operates over the - 40°C to 125°C temperature range. The CSA220 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 CSA220 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 CSA220 particularly useful in a wide range of high - voltage systems.
