IRQ
REF
Hardware Interrupt Output. IRQ can be programmed to pull low when bits in status register
0x00 change state. Read status register 0x00 to clear IRQ once set. Repeat faults have
no effect on IRQ until it is cleared by reading the I
pullup resistor to DVDD for full output swing.
Jack Sense. Detects the insertion of a jack. See the Jack Detection section.
Single-Ended Line Input B1. Also negative differential line input B.
Positive Differential Microphone 1 Input. AC-couple a microphone with a series 1FF
capacitor. Can be retasked as a digital microphone data input.
Single-Ended Line Input A2. Also positive differential line input A or negative differential
external microphone input.
Digital Ground
S2 Digital Audio Bit Clock Input/Output. BCLKS2 is an input when the IC is in slave mode
and an output when in master mode. The input/output voltage is referenced to DVDDS2.
S2 Digital Audio Left-Right Clock Input/Output. LRCLKS2 is the audio sample rate clock
and determines whether audio data on S2 is routed to the left or right channel. In TDM
mode, LRCLKS2 is a frame sync pulse. LRCLKS2 is an input when the IC is in slave mode
and an output when in master mode. The input/output voltage is referenced to DVDDS2.

I
Common-Mode Voltage Reference. Bypass to AGND with a 1FF capacitor.
Low-Noise Bias Voltage. Outputs a 2.2V microphone bias. An external resistor in the 2.2kI
to 1kI range should be used to set the microphone current.
Negative Differential Microphone 1 Input. AC-couple a microphone with a series 1FF
capacitor. Can be retasked as a digital microphone clock output.
Single-Ended Line Input A1. Also negative differential line input A or positive differential
external microphone input.
S2 Digital Audio Serial-Data ADC Output. The output voltage is referenced to DVDDS2.
S2 Digital Audio Interface Power-Supply Input. Bypass to DGND with a 1FF capacitor.
S2 Digital Audio Serial-Data DAC Input. The input voltage is referenced to DVDDS2.
Digital Power Supply. Supply for the digital core and I
1FF capacitor.
Analog Power Supply. Bypass to AGND with a 1FF capacitor.
Converter Reference. Bypass to AGND with a 2.2FF capacitor.
Analog Ground
Negative Differential Microphone 2 Input. AC-couple a microphone with a series 1FF
capacitor.
Positive Differential Microphone 2 Input. AC-couple a microphone with a series 1FF
capacitor.
