综述
The AS8510 data acquisition front-end IC is a virtually offset free, low noise, 2-channel measurement device. It is tailored to accurately measure battery current from mA range up to kA range in combination with a 100 µOhm 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.

本产品适用于以下应用:
- Battery sensor with current sensor in the battery minus rail
- Battery sensor with current sensor in the battery plus rail together with AS8525 zero offset PGA and level translator
- General purpose sensor interface for high accuracy resistive sensors. The 2-channel architecture enables digital error correction techniques like delta by sigma division or capture of bridge current/voltages with subsequent error correction in external µC
- E-scooter battery management
