5 V, SERIAL, 14-BIT 333 KSPS, SAMPLING ADC

Introduction

This Technical Note describes the evaluation board for the AD7851 14-Bit A/D converter. The AD7851 is a high speed, low power ADC which operates from a single +5 V supply. It features self-calibration and system calibration options and also includes a power down mode. It incorporates an on chip track/hold amplifier and a versatile serial I/O port. This flexible serial interface allows the AD7851 to connect directly to Digital Signal Processors (ADSP-2101, TMS320C25, etc.) and Microcontrollers (8XC51, 68HC11, etc.). Full data on the AD7851 is available in the AD7851 data sheet available from Analog Devices and should be consulted in conjunction with this Technical Note when using the Evaluation Board.

On-board components include an REF198; +4.096 V ultra high precision Low Power, Low Dropout reference, an AD845 and two OP-07's amplifiers, an SSM2141 line receiver, and a 74HC08 quad AND gate.

The evaluation board is compatible with the EVALUATION BOARD CONTROLLER.
