GENERAL DESCRIPTION

This user guide details the operation of the evaluation board for

the AD5696R, AD5696, AD5694R, and AD5694 quad channel,

voltage output digital-to-analog converters (DACs).

The E VA L-AD5696RSDZ supports both the AD5696R and

AD5696, and the E VAL -AD5694RSDZ supports both the

AD5694R and AD5694.

AD569x(R) is used in this user guide to refer to the AD5696R,

AD5696, AD5694R, and AD5694.

The evaluation board is designed to help customers quickly

prototype new AD569x(R) circuits and reduce design time.

The AD569x(R) operates from a single 2.7 V to 5.5 V supply.

The AD5696R and AD5694R incorporate an internal 2.5 V

reference to give an output voltage span of 2.5 V or 5 V. T h e

AD5696 and AD5694 require an external reference.

Full data on the AD569x(R) can be found in the appropriate data

sheet available from Analog Devices and should be consulted in

conjunction with this user guide when using the evaluation board.

The evaluation board interfaces to the USB port of a PC via the

SDP board. Software is supplied with the evaluation board to

allow the user to program the AD569x(R).

This evaluation board requires the E VA L -SDP-CB1Z board

(SDP-B controller board), which is available for order on the

Analog Devices website at www.analog.com.

Evaluation Board User Guide UG-532 EVALUATION BOARD HARDWARE POWER SUPPLIES LINK OPTIONS To use the evaluation board with the SDP board, a 6 V power supply is required, which is connected to Connector J3. The evaluation board can be used without the SDP board. In this case, the J1 and J2 connectors are used as the power supply inputs. A number of link options are incorporated in the evaluation board and must be set for the required operating conditions before using the board.

UG-532 Evaluation Board User Guide EVALUATION BOARD SOFTWARE INSTALLING THE SOFTWARE 3. The evaluation kit for the AD569x(R) includes self-installing software on the CD. The software is compatible with Windows® XP, Windows Vista (32-bit), and Windows 7 (32-bit and 64-bit). The software must be installed before connecting the SDP board to the USB port of the PC to ensure that the SDP board is recognized when it connects to the PC.

AD569x(R) Evaluation Board Software Main Window GAIN Control SOFTWARE OPERATION The software for the AD569x(R) allows the user to program values to the input and DAC registers of each DAC individually or collectively. The logic level of the GAIN pin is set externally by LK4 or LK5. To display the correct voltage, the gain selection must be set to match the level of the pin.
