EVAL-AD5790

AD5790 Evaluation Board

产品详情

The Evaluation board for the AD5790 contains a SDP-B connection and software allowing the AD5790 to be controlled from a SDP-B board.


The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.

特性和优点

  • Full featured evaluation board for the AD5780 
  • ADP5070 power solution generated from single 5 V supply
  • Applicable evaluation board for the AD5760 and AD5790 
  • PC control in conjunction with the Analog Devices Inc., EVALSDP-CK1Z (SDP-K1) controller board
  • Various link options

产品详情

The operation of the EVAL-AD5780ARDZ for evaluating the AD5780 (18-bit), bipolar voltage output, digital-to-analog converter (DAC) is detailed in this user guide.

The EVAL-AD5780ARDZ facilitates fast prototyping of the AD5780 circuit, thereby reducing design time. The EVAL-AD5780ARDZ provides an on-board −14 V and +14 V dual power supply. This evaluation board also utilizes external reference boards with an output voltage of +10 V and −10 V.

The EVAL-AD5780ARDZ interfaces with the USB port of a PC via a system demonstration platform (SDP-K1) controller board. The ACE software is available for download on the EVAL-AD5780ARDZ product page. This software enables the user to program the AD5780. A peripheral module interface (PMOD) connection is also available that allows the connection of different microcontrollers to the EVAL-AD5780ARDZ without the SDP-K1 controller board. Note that when a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user cannot use the ACE software.

For full details on the AD5780, see the AD5780 data sheet, which must be used in conjunction with this user guide when using the EVAL-AD5780ARDZ evaluation board.

For added flexibility, the AD5780 can be substituted with either the AD5760 or AD5790, which must be ordered separately.
