2 Analog Interface
Analog Interface
For maximum flexibility, the TLV320DAC32EVM is designed for easy interfacing to the input and outputs
analog signals. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a
convenient 10-pin dual row header/socket combination at J1. These headers/sockets provide access to
the analog input and output pins of the device. Consult Samtec at www.samtec.com or call
1-800-SAMTEC-9 for a variety of mating connector options. Table 1 summarizes the analog interface
pinout for the TLV320DAC32EVM.

In addition to the analog headers, the analog inputs and outputs may also be accessed through alternate
connectors, either screw terminals or audio jacks. The line input is connected via J8 and the stereo
headphone output (the HP set of outputs) is available at J9.
Table 2 summarizes the screw terminals available on the TLV320DAC32EVM.
