General Overview

This evaluation board provides the user with a simple and quick solution to evaluate digital potentiometers from Analog Devices.

How to Get Started

Load the CD and click on setup.exe.

Use power from the parallel port or apply an external power supply refer to “Powering Options” to avoid damaging the part and computer port .

Connect board to parallel port with the provided connector and cable.

Open the AD5258/59Eval_RevX program from the Windows Start menu.

Powering Options

A. Using the power from the parallel port. Connect JPVDD jumper. This will power VDD. Connect JPVLOGIC jumper. This will power VLOGIC.

B. Using an external power supply must be at least +2.7V * DO NOT connect JPVDD and JPLOGIC jumpers. Connect JPPOWER jumper. Connect voltage supply power and ground to the VDD and GND pads on the board.
*If two independent supplies are being for VDD and VLOGIC, do not connect JPPOWER. Simply apply the two power supplies to VDD, VLOGIC, and GND pads on the board.

How to Use Software Interface

In the ‘Enter Data’ box, either type in the value, use the scroll bar, or click a preset button. Note that this is simply a data entry box and does not perform any function on the digital potentiometer device. Communication with the device occurs in Steps 2 and

In the ‘Write/Restore/Store’
i. Click on ‘Write to RDAC’ to write value chosen in Step 1 to the RDAC. ii. Click on ‘Write to EEMEM’ to write value chosen in Step 1 to the EEMEM. iii. Click on ‘Restore EEMEM Content to RDAC’ to restore current EEMEM content to RDAC. iv. Click on ‘Store RDAC Content to EEMEM’ to store current RDAC setting to EEMEM.

In the ‘Read Data’
i. Click on ‘Read from RDAC’ to read back current setting of RDAC. ii. Click on ‘Read EEMEM’ to read back current content of EEMEM. iii. Click on ‘Read Tolerance’ to read back the tolerance of the resistance RAB. For example, if the
device is the device is a option and the tolerance readback is that would mean the actual value of RAB =
