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 also tied to J8 and the headset output tied to J11. Table 2 summarizes the screw terminals available on the TLV320AIC12KEVMB/14KEVMB.

3Digital Interface

The TLV320AIC12KEVMB/14KEVMB is designed to easily interface 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 at J4 and J5. These headers/sockets provide access to the digital control and serial data pins of the device. Consult Samtec at www.samtec.com or call 1-800- SAMTEC-9 for a variety of mating connector options. Table 3 summarizes the digital interface pinout for the TLV320AIC12KEVMB/14KEVMB.
