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 microphone input is tied to J9. Table 2 summarizes
the screw terminals available on the TLV320AIC1106EVM.

The TLV320AIC1106EVM is designed to interface easily with multiple control platforms. 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. These headers/sockets provide access to the digital control and serial data
pins of the device. Table 3 summarizes the digital interface pinout for the TLV320AIC1106EVM.
