Overview
The AD7863AR-3REEL7 is a high-speed, low-power, dual 14-bit analog-to-digital converter (ADC) produced by Analog Devices, Inc. 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 AD7863AR-3REEL7 is fabricated in the Analog Devices linear compatible CMOS (LC2MOS) process, combining precision bipolar circuits with low power CMOS logic. It is available in a 28-lead SOIC package and is suitable for a variety of applications, including battery-powered and portable devices, due to its automatic power-down mode.
