Analog Input

Last Modified: August 8, 2019

The analog input section consists of two identical banks of analog inputs which are capable of operating independently of each other. Each bank includes an analog-to-digital converter (ADC), conditioning circuit, gain selector, mode selector, and channel multiplexer. The gain stage determines the input range for the conversion. The mode selection controls whether the input is configured for single-ended or differential measurement. The channel multiplexer selects the active channel(s) for the application.
