描述

The AS89020 is a 12-bit, 4-channel, current input Analog-to-Digital Converter (ADC). It combines current-to-voltage (TIA) and analog-to-digital (AD) conversion, so that 4 separate current output devices (e.g. photodiodes) can be directly connected to its inputs and digitized.
For each of the 4 inputs the AS89020 provides an input amplifier with a track and hold circuit. The outputs of the track and hold stages are serial converted to 12-bit digital words using an analog-to-digital converter (ADC).
