Product Usage Instructions

Power Supply Options
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ board can be powered using the on-board ADP5071 or from well-regulated bench supplies.

Using On-Board Power Supply (ADP5071)
The ADP5071 switching regulator provides bipolar supply of +8 V and -22 V from a +3.3 V input. This generates a DAC voltage output range of -20 V to +6 V. Alternatively, linear power supply via AVDD_SEL and AVSS_SEL can be used to generate all ranges.

Power Supply Connections
The board requires four power supplies: AVDD, AVSS, AVCC, and VLOGIC. Ensure correct connections for proper functionality.

ACE Software Operation
The ACE Software offers an intuitive GUI for configuring the modes of operation for AD5766/AD5767. Refer to the software manual for detailed instructions.

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 onboard 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 requires 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 conjunction with this user guide when using the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ.

EVALUATION BOARD HARDWARE

POWER SUPPLIES AND DEFAULT LINK OPTIONS
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation board can be powered using the onboard ADP5071 or from well-regulated bench supplies. See Table 1 for the onboard jumper configurations for each power supply solution.
Table 1. Jumper Configurations for the ADP5071 and Bench Supply

The on-board ADP5071, supplied with a 3.3 V supply via the PWR_SEL connector, or the supply from the SDP-K1 (in this configuration, make sure to supply AVCC externally; AVCC_SEL: 2-3), can power the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards. Alternatively, the evaluation boards can also be powered externally; AVDD and AVSS through the P8 connector while AVCC uses the EXT_AVCC connector. See Figure 3 for a functional block diagram of the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards.
For either power supply option, place the links in their required operating setup before supplying the evaluation boards (see Table 3).

Table 2. Quick Start on Power Supply Requirements for the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ

ADP5071 POWER SOLUTION OPTION
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards are populated with the ADP5071 switching regulator. This regulator generates +8 V and −22 V supplies. The ADP5071 data sheet recommends 3.3 V for correct operation.
Two ways to power the ADP5071 are available using the PWR_SEL options. First, use an external 3.3 V supply (recom-mended). This method involves connecting an external 3.3 V supply, which provides a stable and reliable power source, especially for more demanding applications. This method is recommended for most cases to ensure optimal performance. The other option is to use the SDP-K1 as the power supply.
To select the power source for AVCC, use the AVCC_SEL jumper. Position 1-2 on AVCC_SEL ties AVCC and the ADP5071 supplies together to operate from a single 3.3 V supply. Alternatively, Position 2-3 on AVCC_SEL powers AVCC with an external supply via the EXT_AVCC connector. Refer to Table 3 for all the link options. Note that the −12 V to +14 V, −16 V to +10 V, or −10 V to +10 V output voltage ranges are not available with the default configuration of the ADP5071 because a minimum of 2 V headroom is required.
Table 3. Link Options

BENCH POWER SUPPLY OPTION
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards can access all output voltage ranges of the AD5766/AD5767 when powered by a bench supply. A headroom and footroom of at least 2 V is required. Refer to Table 2 for the supply requirements. It is
important that the voltage across AVDD to AVSS does not exceed the absolute maximum rating of 34 V. Otherwise, device reliability may be affected.
Following the jumper configuration in Table 1 and Table 3 gives more details about the options offered. For VLOGIC, users can use the 3.3 V provided by the SDP-K1 controller board when interfaced with the USB port of a PC or use an external power supply interfaced with Pin 11 or Pin 12 (VIO) of the peripheral module (PMOD, P6).

ON-BOARD CONNECTORS
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards have various on-board connectors for the external power supplies and header pins, and these connectors are described in detail in Table 4.
Table 4. On-Board Connectors

PMOD Connector (P6) Pin Descriptions
The PMOD connector allows the user to control the EVAL-AD5766ARDZ/EVAL-AD5767ARDZ by means of communicating with the AD5766/AD5767 through the 12 pins of P6. For further information on the functionality of the P6 pins, see Table 5.
Table 5. Connector P6 Pin Descriptions

EVALUATION BOARD SOFTWARE

ACE SOFTWARE INSTALLATION
The EVAL-AD5766ARDZ/EVAL-AD5767ARDZ evaluation boards use the Analog Devices Analysis | Control | Evaluation (ACE) Software, a desktop software application that allows the evaluation and control of multiple evaluation systems.
The ACE Software is available for download from the EVAL-AD5766ARDZ and EVAL-AD5767ARDZ evaluation board pages and must be installed before connecting the EVAL-SDP-CK1Z (SDP-K1) controller board to the USB port of the PC to ensure that the EVAL-SDP-CK1Z (SDP-K1) is recognized when it connects to the PC. The ACE installer installs the necessary SDP drivers and the Microsoft® .NET Framework 4 by default. For full instructions on how to install and use this software, see the ACE Software page on the Analog Devices website.
After the ACE Software installation is completed and the user opens this software, the EVAL-AD5766ARDZ or EVAL-AD5767ARDZ evaluation board plug-in appears.

ACE SOFTWARE OPERATION
To use the ACE Software with the AD5766 or AD5767, take the following steps:

To launch the ACE Software, click Start > All Programs > Analog Devices > ACE. The ACE Software then opens in the Start tab and recognizes the EVAL-AD5766ARDZ. Note that the interface is the same for the EVAL-AD5767ARDZ, except for the board name (see Figure 4).
Double-click the EVAL-AD5766ARDZ icon under the Attached Hardware section to open the EVAL-AD5766ARDZ tab (see Figure 4 and Figure 5).
Double-click the AD5766 icon to open the AD5766 chip tab (see Figure 6). This tab displays the block diagram and allows the user to configure the digital-to-analog converter (DAC) input registers and control registers. The hardware registers on the AD5766/AD5767 are not altered until the Apply Changes button is clicked.
Click Proceed to Memory Map (Label 12 in Figure 8) to open the AD5766 Memory Map tab and allow access to all registers (see Figure 7). The hardware registers on the AD5766 or AD5767 are not altered until the Apply Changes button is clicked.

For a detailed description of all GUI options, see Figure 8 and Table 6.
