2.2.1 Theory of Operation for SM-USB-DIG Platform
Figure 4 shows the block diagram for the SM-USB-DIG platform. This platform is a general-purpose data
acquisition system that is used on several different Texas Instruments evaluation modules. The details of
its operation are included in a separate document, SBOU098 (available for download at www.ti.com). The
block diagram shown in Figure 4 gives a brief overview of the platform. The primary control device on the
SM-USB-DIG platform is the TUSB3210.

3 TMP112EVM Hardware
The TMP112EVM hardware overview involves connecting the two PCBs of the EVM together, connecting
the USB cable, applying power, and setting the jumpers. This section presents the details of this
procedure.
3.1 Electrostatic Discharge Warning
CAUTION
Many of the components on the TMP112EVM 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.
