AD7891-2CB is a Single Supply, 12-Bit 500 kSPS ADC Evaluation Board with full-featured, EVAL-CONTROL BOARD compatible, stand-alone capability, on-board analog buffering and reference, and various linking options.
The document provides an overview of the EVAL-AD7891-2CB, a full-featured evaluation board designed for the AD7891-2 eight-channel data acquisition system. Key features include stand-alone capability, on-board analog buffering using AD713 op-amps, and compatibility with the EVAL-CONTROL BOARD via various linking options.
The guide details the operating procedures, including power supply requirements (VDD, +12V, -12V) and ground connections. It explains how to configure thirty-one link switches to select input voltages, reference sources, and interface modes (serial or parallel). Additionally, it describes the interfacing methods using a 96-way connector for parallel operation or a 9-way D-type connector for serial communication.
The device accepts input signals in the ranges of 0 to +5 V, 0 to +2.5 V, or 0 to -2.5 V.
Link LK1 should be in position A, while links LK2 through LK8 must be set to position B.
