1 Evaluation Module Overview
1.1 Introduction
The DACx050x is a pin-compatible family of low-power, multi-channel, buffered voltage output, digital to-analog
converters (DAC). The DACx050x includes a 2.5-V, 5-ppm/°C internal reference, eliminating the need for an
external precision reference in most applications. A users-selectable gain configuration provides full-scale output
voltages of 1.25 V (gain = ½), 2.5 V (gain = 1) or 5 V (gain = 2). The device operates from a single 2.7-V to 5.5-V
supply, is specified monotonic, and provides high linearity of ±1 LSB INL.
Communication to the DACx050x is performed through a serial interface that operates at clock rates up to
50 MHz. The VIO pin enables serial interface operation from 1.7 V to 5.5 V. The DACx050x flexible interface
enables operation with a wide range of industry-standard microprocessors and micro-controllers.
The DACx050x incorporates a power-on-reset circuit that powers up and maintains the DAC outputs at either
zero-scale or mid-scale until a valid code is written to the device. The devices consume low current of 0.6
mA/channel at 5.5 V, making the devices an excellent choice for battery-operated equipment. A per-channel
power down feature reduces the device current consumption to 15 µA.
This user's guide describes the characteristics, operation, and recommended use cases of the
DAC80508-04EVM. This document provides examples and instructions on how to use the DAC80508-04EVM
board and included software. Throughout this document, the terms evaluation board, evaluation module, and
EVM are synonymous with the DAC80508-04EVM. This document also includes schematics, the reference
printed circuit board (PCB) layouts, and a complete bill of materials (BOM).

2 Hardware
2.1 Hardware Setup
This section describes the overall system setup for the EVM. A computer runs software that communicates with
the FTDI controller onboard using SPI protocol.
2.1.1 Hardware Theory of Operation
The DAC80508-04EVM is connected to the computer through the on-board FTDI digital controller using the
USB cable that is supplied with the EVM. The evaluation board features connectors and test points for all
communication lines, DAC outputs, and supplies. Figure 2-1 shows a block diagram of the DAC80508-04EVM.

Figure 2-1. Theory of Operation Block Diagram
The USB connection provides the 5-V supply to the EVM. Voltage regulators generate 3.3 V and 1.8 V from the
USB 5-V supply. These 3.3-V and 1.8-V supplies are used to power the FTDI controller.
The VDD supply can use the on-board 5-V or 3.3-V supplies depending on the jumper J6 setting. By default,
VDD is connected to the on-board 5-V supply. Alternatively, VDD can be supplied externally through banana jack
J4. Remove the jumper connector on J6 before connecting external supplies to VDD.
The VIO supply can use the on-board 1.8 V or use the same voltage as VDD depending on the jumper J5
setting. By default, VIO is connected to VDD. Alternatively, VIO can be supplied externally through banana jack
J8. Remove the jumper connector on J5 before connecting external supplies to VIO.
The device reference voltage can be supplied via an onboard 2.5-V voltage regulator by shorting jumper J12,
or from an external supply with SMA connector J10. Make sure that the internal reference is powered off before
connecting any other voltage supply to the REF pin.
Each of the DAC outputs have footprints available for capacitor and resistor loads that are unpopulated by
default.

2.2 Hardware Overview
This section details how to configure the EVM for voltage outputs using SPI. The following subsections provide
detailed information on the EVM hardware.
2.2.1 Electrostatic Discharge Caution
CAUTION
Many of the components on the DAC80508-04EVM are susceptible to damage by electrostatic
discharge (ESD). Customers are advised to observe proper ESD handling precautions when
unpacking and handling the EVM, including the use of a grounded wrist strap at an approved ESD
workstation.
2.2.2 Connecting the FTDI Digital Controller
To connect the FTDI digital controller on the EVM board to the computer, align and firmly connect the USB
connector to the J3 connector. Verify the connection is snug; a loose connection can cause intermittent
operation. A 100 mil header (J15) is available for external communication. Table 2-6 lists the J15 pin definitions.
To use external communication, close jumper J1 to disable the connection to the FTDI controller.

Additionally, the board has a dedicated 100 mil header for the DAC80504 digital pins. The DUT connects to this
header with 0 Ω resistors, which are unpopulated by default. If the DAC80504 is used, then TI recommends to
populate R29, R30, R31, and R32 to connect the GAIN, RSTSEL, REFDIV, and LDAC to the FTDI and digital
header. Table 2-7 lists the pin definitions.

3 Software
3.1 Software Setup
This section provides the procedure for EVM software installation.
3.1.1 Software Installation
Note
Do not connect the EVM to the computer while the software is installing.
Download the latest version of the EVM graphical user interface (GUI) installer from the Order and start
development subsection of the DAC80508-04EVM tool folder on TI.com. Run the GUI installer to install the
DAC805xxEVM GUI software on your computer. The software installation automatically copies the required
LabVIEW™ software files and drivers to the computer.
When the DAC805xx GUI is launched, an installation dialog window opens and prompts the user to select an
installation directory. If left unchanged, Figure 3-1 shows that the software location defaults to C:\Program Files
(x86)\Texas Instruments\DAC805xxEVM.

The EVM software also installs the Future Technology Devices International Limited (FTDI) USB drivers using
a separate executable file. Figure 3-2 shows the FTDI USB drivers installation window that is automatically
launched after the DAC805xxEVM software installation is complete.

3.2 Software Overview
This section discusses how to use the DAC805xxEVM software.
3.2.1 Launching the Software
If installed in the default directory, then launch the DAC805xxEVM software by searching for DAC805xxEVM
GUI in the Windows® Start menu.
Figure 3-3 shows the Device Setting configuration menu that is present when the GUI is launched. Select either
the DAC80504 or DAC80508 device from the drop-down menu and click CONFIG. The software only supports
one device at a time.

3.2.2 Software Features
The DAC805xxEVM GUI allows for SPI communication to the DAC80508 or DAC80504 and control of the digital
pins. Although the entire register map is available for use, some features have been abstracted into user controls
in the High-Level Configuration page for easy operation.
3.2.2.1 Low Level Configuration Page
Figure 3-7 shows the Low Level Configuration page of the DAC805xxEVM GUI with the DAC80504 device
selection. This page allows direct access to all registers on the DAC80504. Figure 3-8 shows the Low Level
Configuration page for the DAC80508.
The Register Map section in the center of the page lists all the registers. Directly above the Register Map section
are four buttons that allow for read and write access to all registers.
Select a register on the Register Map list to show a description of the values in that register, as well as
information on the register address, default value, size, and current value. Data are written to the registers by
entering a value in the value column of the GUI.

3.2.2.2 High Level Configuration Page
The High Level Configuration page is used to set the configuration of the DAC805xxEVM GUI. The page is
comprised of one tab: DAC80504 if the DAC80504 device was selected, or DAC80508 if the DAC80508 device
was selected. These two tabs act as shortcuts to configure the DAC80504 and DAC80508 for basic functionality
and testing.
Figure 3-9 shows the DAC80504 tab of the High Level Configuration page. This tab is used to set the gain
and output for the DACs. The DAC80504 digital pins can also be controlled here. To use the digital pin GUI
functionality, resistors R29, R30, R31, and R32 are required to be populated with 0 Ω resistors. These resistors
connect the digital pins to the FTDI GPIO pins. By default, the GAIN, REFDIV, and RSTEL GPIOs are set to 0 V.
If the GAIN, REFDIV, or RSTSEL options are changed, the DAC80504 needs to go through a power-on-reset for
the changes to take effect. Do not unplug the USB cable to reset the power, as this resets the GPIO pins as well.
The internal reference and the reference division can also be powered on and off here.
Figure 3-9. DAC80504 Tab of the High Level Configuration Page
Figure 3-10 shows the DAC80508 tab from the High Level Configuration page. This tab is used to set the gain
and output for the DACs. The internal reference and the reference division can also be powered on and off here.
