AN-1115 Analog Decoder for Single Wire Multi-Key Detection

This application note will explain how to build a multi-level comparator for single wire, multi-key detection using three components in GreenPAK™4: the ADC block, the digital comparator (DCMP) and the analog comparator (ACMP). This concept is useful when trying to decode an analog input voltage that varies with external circumstances.
