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.
