EVAL-AD5696RARDZ

製品概要

This user guide details the operation of the EVAL-AD5686RARDZ (serial peripheral interface (SPI)) evaluation board and the EVALAD5696RARDZ (I²C) evaluation board for the AD5686R (SPI) and the AD5696R (I²C), respectively, which are both quad-channel, voltage output digital-to-analog converters (DACs).

The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ are designed to facilitate quick prototyping of the AD5686R circuit and the AD5696R circuit, respectively, thereby reducing design time. Both devices operate from a single 2.7 V to 5.5 V supply. Additionally, these devices also incorporate an internal 2.5 V reference. However, if required, a different reference voltage can be applied via the EXT_REF SMB connector. Although these two DACs share common features, they differ in their digital interface protocols. The AD5686R uses SPI whereas the AD5696R uses I²C.

The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ interface with the USB port of a PC via a system demonstration platform (SDP) controller board. The analysis, control, evaluation (ACE) software is available for download from both the EVAL-AD5686RARDZ product page and the EVAL-AD5696RARDZ product page. The ACE software can be used with the EVAL-AD5686RARDZ or the EVAL-AD5696RARDZ to allow the user to program the AD5686R and the AD5696R, respectively. A PMOD connection can also be found on the evaluation board to allow the connection of microcontrollers without the SDP controller board. Note that when a microcontroller is used through the PMOD connection, the SDP controller board must be disconnected. Therefore, the user cannot use the ACE software.

The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which is available for purchase from Analog Devices.

For full details, see the AD5686R data sheet or the AD5696R data sheet, which must be consulted in conjunction with this user guide when using either the EVAL-AD5686RARDZ or the EVALAD5696RARDZ.
