The following documents provide information regarding Texas Instruments integrated circuits used in the assembly of the PGA308EVM. These documents are available from the TI web site under the respective literature number (for example, SBxxnnn). Any letter appended to the literature number corresponds to the document revision that is current at the time of the writing of this User’s Guide.
Related Documentation from Texas Instruments. The PGA308EVM is an evaluation module that is used to fully evaluate the PGA308 device. The PGA308 is a mixed-signal programmable gain amplifier that has high resolution gain and offset adjustment capability. The PGA308EVM consists of two PCBs. One board generates the digital signals (USB DAQ Platform) required to communicate with the PGA308 (PGA308_Test_Board), and the second board contains the PGA308, as well as support and configuration circuitry.
PGA308EVM Hardware Figure 1-1 shows the hardware included with the PGA308EVM kit. Contact the factory if any component is missing. TI highly recommendeds that you check the TI web site (at http://www.ti.com) to verify that you have the latest software.
System Setup Figure 2-1 shows the system setup for the PGA308EVM. The PC runs software that communicates with the USB DAQ platform. The USB DAQ platform generates the digital signals used to communicate with the PGA308 test board. Connectors on the PGA308 test board allow for connection to the system that will be monitored by the user.
Theory of Operation For the USB DAQ Platform Figure 2-3 shows the block diagram for the USB DAQ platform. This platform is a general-purpose data acquisition system that is used on several different Texas Instruments evaluation modules. The block diagram shown in Figure 2-3 illustrates the general platform outline.
SBOU060A – July 2008 – Revised September 2016 Hardware Connections and Jumper Settings Many of the components on the PGA308EVM 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.
Connecting the Hardware www.ti.com Connecting the Hardware The best way to connect the two PGA308EVM PCBs together is to gently push on both sides of the DSUB connectors, as shown in Figure 3-2. Make sure that the two connectors are completely socketed together;...
Connecting Power www.ti.com Connecting Power Connect the two PGA308EVM PCBs before connecting a power source, as shown in Figure 3-3. Always connect power before connecting the USB cable. If the USB cable is connected before the power is supplied, the computer will attempt to communicate with an unpowered device, and the device will not be able to respond.
Connecting the USB Cable to the PGA308EVM www.ti.com Connecting the USB Cable to the PGA308EVM Figure 3-4 shows the typical response to connecting the USB DAQ platform to a PC USB port for the first time. Note that the EVM must be powered up before connecting the USB cable. Typically, the computer will respond with a Found New Hardware, USB Device pop-up.
Jumper Settings Figure 3-5 shows the default jumper configuration for the PGA308EVM. In general, the jumper settings of the USB DAQ platform do not need to be changed. However, you may want to change some of the jumpers on the PGA308 test board to match your specific device configuration (for example, to change the reference configuration).
PGA308EVM Software Install Install the PGA308EVM software by following these steps: 1. Software can be downloaded from the PGA308EVM web page, or from the disk included with the PGA308EVM, which contains a folder called Install_software/. 2. Find the file called setup.exe. Double-click the file to start the installation process.
Use the Windows Start menu to start the PGA308 software. From Start, select All Programs, then select the PGA308EVM program. Figure 4-1 shows the software display if the EVM is functioning properly.

DSUB connectors are completely pushed together. Another possible cause for this error is it that the PGA308 test board jumpers are set in the wrong positions. Figure 4-3. PGA308EVM Software—No Communication from USB DAQ Platform to PGA308 PGA308 Software Overview SBOU060A –...
Using the PGA308 Software The PGA308EVM software has six different tabs that allow you to access different features of the PGA308. Each of these tabs are intended to have an intuitive graphical interface that allows users to develop a better understanding of the PGA308.
