EVAL-AD5693RARDZ

Evaluation Board for AD5693R (I2C, MSOP)

特性和优点

  • Full-featured evaluation boards for the AD5693R (I2C, MSOP)
  • On-board reference
  • Various link options
  • PC control in conjunction with the Analog Devices, Inc., EVALSDP-CK1Z (SDP-K1) controller board

产品详情

This user guide details the operation of the EVAL-AD5683RARDZ (serial peripheral interface (SPI)) evaluation board and the EVALAD5693RARDZ (I2C) evaluation board for the AD5683R (SPI) and the AD5693R (I2C), respectively, which are both single-channel, serial voltage output digital-to-analog converters (DACs).

The EVAL-AD5683RARDZ and the EVAL-AD5693RARDZ are designed to facilitate quick prototyping of the AD5683R and AD5693R circuits, 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 on-board reference. A different reference voltage can be applied via the EXT_REF SMB connector, if required. While sharing common features, the two DACs differ in their digital interface protocols. The AD5683R employs SPI, while the AD5693R employs I2C.

The EVAL-AD5683RARDZ and the EVAL-AD5693RARDZ interface with the USB port of a PC via the System Demonstration Platform (SDP) controller board (EVAL-SDP-CK1Z (SDP-K1)). The Analysis | Control | Evaluation (ACE) software is available for download from both the EVAL-AD5683RARDZ product page and the EVALAD5693RARDZ product page. This software can be used with either evaluation board to allow the user to program the AD5683R and AD5693R, respectively. A PMOD connection is also available to allow the connection of a microcontroller to either evaluation board. Note that when a microcontroller is used through the PMOD connection, the EVAL-SDP-CK1Z (SDP-K1) must be disconnected, and the user cannot use the ACE software.

The EVAL-AD5683RARDZ and the EVAL-AD5693RARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which is available for purchase from Analog Devices.

For full details on the AD5683R and the AD5693R, see the AD5683R and AD5693R data sheets, which must be consulted in conjunction with this user guide when using either of the EVALAD5683RARDZ or the EVAL-AD5693RARDZ evaluation boards.
