By ams 17
The ams AS8510 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 μΩ 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. It offers for each channel a programmable gain amplifier with four gain stages followed by a 16-bit Σ Δ AD converter.
The device includes a number of additional application specific features such as digital filter to shape the signal paths frequency response, operating mode selection including low power current monitoring with wake function through threshold comparator, internal precision reference, RC clock generator for normal- and low-power modes, interrupt output for device synchronization, and timers for single shot sampling.
