製品概要The EVAL-AD7903SDZ is an evaluation board designed to demonstrate the low power AD7903 performance and to provide an easy to understand interface for a variety of system applications. The AD7903 is a dual differential 16-bit, 1 MSPS PulSAR® ADC. A full description of the AD7903 is available in the AD7903 data sheet and should be consulted when using this evaluation board.
The evaluation board is ideal for use with the Analog Devices, Inc., system demonstration platform (SDP) board, EVAL-SDP-CB1Z. The evaluation board interfaces to the SDP board via a 120-pin connector. SMA Connectors J6, J7, J10, and J15 are provided to connect a low noise analog signal source.
The user PC software executable controls the evaluation board over the USB through the SDP board, EVAL-SDP-CB1Z.
On-board components include the following:
ADR435: high precision, buffered band gap 5.0 V reference
AD8031: reference buffer
ADA4841-1: signal conditioning circuit with op amps
