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.
CAUTION
Failure to observe ESD handling procedures may result in damage to EVM
components.
3.1
Typical Hardware Connections
A typical PGA308EVM hardware setup connects the two EVM PCBs, then supplies power and connects
an external shunt and load. The external connections may be the real-world system to which the PGA308
will be connected. Figure 3-1 shows the typical hardware connections.

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;
loose connections may cause intermittent EVM operation.

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.
Connect 6 V to 9 V DC to T3

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. The pop-up typically changes to Found
New Hardware, USB Human Interface Device. This pop-up indicates that the device is ready to be used.
The USB DAQ platform uses the Human Interface Device Drivers that are part of the Microsoft Windows
operating system. In some cases, the Windows Add Hardware Wizard will pop-up. If this prompt occurs,
allow the system device manager to install the Human Interface Drivers by clicking Yes when requested to
install drivers.
Turn on PC sound. Connect USB
connector J1 to PC USB Port.
These messages may appear the first time
the EVM is used.

Figure 4-2 shows an error that appears if the computer cannot communicate with the EVM. If this error
occurs, check to see that the USB cable is connected. This error can also happen if the USB cable is
connected before connecting the USB DAQ platform 9V power supply. Another possible reason for this
error message is a problem with the USB human interface device driver of the computer. Make sure that
the computer recognizes the device when the USB cable is plugged in. If the sound is on, you will hear
the distinctive sound that you expect when a USB device is properly connected to a PC with the Windows
operating system.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
