特性和优点

产品详情

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-toanalog 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 (SDPK1) 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/EVALAD5767ARDZ 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 conjunction with this user guide when using the EVAL-AD5766ARDZ/ EVAL-AD5767ARDZ.
