Analog DevicesEVAL-AD7492SDZDatenkonvertierung, Entwicklungsplatinen und -kits

The EVAL-AD7492SDZ is a full-featured evaluation board, designed to allow the user to easily evaluate all features of the AD7492. The evaluation board can be controlled via the system demonstration platform (SDP) connector (J1). The SDP board allows the evaluation board to be controlled via the USB port of a PC using the AD7492 evaluation software.
On-board components include the AD8597 ultralow distortion, ultralow noise operational amplifier (single); the AD8021 low noise, high speed amplifier for 16-bit systems; the ADP1613 650 kHz/1.3 MHz step-up PWM dc-to-dc switching converter with 2.0 A current limit; the ADP3303-5 high accuracy anyCAP™ 200 mA low dropout linear regulator; and the ADP2301 1.2 A, 20 V, 1.4 MHz nonsynchronous step-down switching regulator.
The evaluation board features analog bias-up circuitry. Bipolar signals are input via the SK3 SMB connector and are biased up by the on-board bias-up buffer circuit. The biased up signal is available at the VIN SMB and can be applied to the VIN input of the AD7492 device by placing the LK10 link in Position A.
Various link options are described in the Evaluation Board Hardware section. The Parallel Interface section of this user guide should be consulted when configuring the board for standalone operation.
