Datasheet Summary
Data Acquisition System with Power Management and LIN Transceiver for 12V Battery Sensor Applications
1 General Description
The AS8515 is designed for simultaneous measurement of shunt current sensor signal and battery voltage by two independent ADC channels. Both channels can measure small signals up to ±219 mV versus ground through programmable gain amplifier or larger signals in the 1V range without amplifier. After analog to digital conversion and digital filtering, the resulting digital values are accessible through 4-wire serial interface. The device is powered directly from the battery through LDO and provides a 3.3V supply for an external microcontroller. For...
