Overview
The AD7863ARSZ-10, produced by Analog Devices Inc., is a high-speed, low-power, dual 14-bit analog-to-digital converter (ADC). This component operates from a single 5 V supply and is designed for simultaneous sampling and conversion of two channels. It features two complete ADC functions, each with a two-channel input multiplexer, allowing for the preservation of the relative phase information of the signals on both analog inputs. The AD7863 is fabricated using the linear compatible CMOS (LC2MOS) process, combining precision bipolar circuits with low power CMOS logic.
