Data-acquisition IC accurately measures battery current

The ams AS8510 data acquisition front-end IC is - a virtually offset free, low noise, 2-channel measurement device - is now available om Digi-Key. The device is tailored to accurately measure battery current from mA range up to kA range in combination with a 100uohm shunt resistor connected in series with the battery rail. Through the second measurement channel, it enables capture of either battery voltage synchronous with the current or to measure the analog output of an internal or external temperature sensor.
