The AS8512 is a virtually offset free, low noise, two channel measurement device. It is tailored
to accurately measure battery current from mA range up to kA range in conjunction with a
100 μΩ shunt resistor in series with the battery rail. Through the second measurement channel
it enables capture of, either battery voltage synchronous with the current measurement, or,
measure the analog output of an internal or external temperature sensor. Both channels are
matched and can either measure small signals up to ±160 mV versus ground, through
programmable gain amplifier or larger signals in the 0 to 1V range without the amplifier.
After analog to digital conversion and filtering, the resulting 16-bit data is accessible via 4-wire
standard serial interface (SPI).
