Analog Devices AN-366 AD7711 Evaluation Board Application Note
This document describes the evaluation board for the AD7711, a 24-bit sigma-delta A/D converter offering 16-bit accuracy. The board includes an AD680 reference, a 10 MHz crystal, and bus buffers to facilitate connection to digital signal processors and microcontrollers. Full data on the AD7711 is provided in the separate AD7711 data sheet.
The note details various link options on the board to configure the serial interface mode, master clock source (on-board crystal or external), and reference sources (internal, AD680, or external). It also covers power supply requirements, grounding strategies, and analog input section configurations.
