GENERAL DESCRIPTION

The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ are fully featured

evaluation boards designed to easily evaluate all features of the

AD5766/AD5767 16‑channel, 16-bit/12-bit, voltage output digital-to-

analog converters (DACs).

These evaluation boards integrate a power solution using the

ADP5071. The ADP5071 switching regulator offers a power solution

by generating a bipolar supply of +8 V and −22 V from a +3.3

V input to create a DAC voltage output range of −20 V to +6 V.

Alternatively, supplying the DAC with a linear power supply via

AVDD_SEL and AVSS_SEL generates all ranges.

The on-board connector, via P6, or the EVALSDP-CK1Z (SDP-

K1) system demonstration platform (SDP) board, can control the

AD5766/AD5767. The SDP-K1 enables the control of the evaluation

boards through the USB port of a Windows

®-based PC using the

AD5766/AD5767 evaluation software, ACE.

The AD5766/AD5767 are 16-channel, 16-bit/12-bit, voltage output

denseDAC

® converters. The DACs generate output ranges from

a 2.5 V reference. Output buffers permit the AD5766/AD5767 to

source or sink up to 20 mA.

The AD5766/AD5767 require four power supplies. AVDD and AVSS

are the positive and negative high voltage power supplies, AVCC is

the analog supply for the low voltage DAC circuitry, and a VLOGIC

supply pin sets the logic levels for the digital interface pins.

The ACE Software of the EVAL-AD5766ARDZ/EVAL-

AD5767ARDZ has an intuitive graphical user interface (GUI) for

the configuration of AD5766/AD5767 modes of operation. Visit the

ACE Software page to view the plug-in modules for the evaluation

boards of many other Analog Devices devices.

Complete specifications for the AD5766/AD5767 are available in

the AD5766/AD5767 data sheet, which must be consulted in con-

junction with this user guide when using the EVAL-AD5766ARDZ/

EVAL-AD5767ARDZ.
