The IRL5111FI is a 12-bit data acquisition system with 8-channel analog inputs. Each analog input channel consists of an overvoltage protection circuit, a multiplexer with automatic or manual scanning. The device features a 4.096-V internal reference and operates from a single 5-V analogue supply. Each channel can be individually programmed for processing bipolar input ranges (± 0.64V; ±10.24V) in single-ended or differential modes or unipolar ranges from 0 to 1.28-10.24V single-ended or from 0 to 0.64-10.24 V differential.
