when using two Headphones simultaneously. See electrical specifications for details.
Note
result in significant audio quality degradation of the microphone audio input. In particular, when the
40dB MIC boost is active, the SNR, THD+N and DC offset will significantly degrade regardless of the
input signal level.
Audio Jack Presence Detect
SENSE_A pin is used to detect the presence of plugs in ports A, B, C, and D. SENSE_B pin is used
to detect the presence of plugs in ports E, F, G, ad H. Refer to the reference design for port detect
circuitry. Select the precision of the resistors used as follows:
