AD7891-1CB is an evaluation board for Analog Devices' single supply, 12-bit 454 kSPS ADC. It supports the EVAL-CONTROL BOARD, has stand-alone capability, onboard analog buffering and reference, and various linking options. When used with the EVAL-CONTROL BOARD, it can be controlled and data analyzed using PC software.
The document provides an overview of the EVAL-AD7891-1CB, a full-featured evaluation board designed for the AD7891-1 twelve-bit A/D converter. Key features include stand-alone capability, on-board analog buffering using AD713 quad op-amps, and compatibility with the EVAL-CONTROL BOARD via various linking options.
The guide details the configuration of thirty-one link switches (LK1-LK31) required to set up the board for specific operating modes. It explains how these links control input voltages, reference sources, power supplies, and interface selection between serial and parallel modes.
The device accepts input signals in the range of +5 V or ±10 V.
There are thirty one link options that must be configured for the required operating setup.
In position A, the STANDBY pin is connected to VDD.
