NAME
FUNCTION
37
DVDDS2
Secondary Digital Audio Interface Power-Supply Input. Bypass to DGND with a 1F
capacitor.
38
MCLK
13MHz/26MHz Master Clock Input
39
VIBE
Transducer/Vibrator Output. Open-drain output programmable to control a vibrator motor
or a transducer. Connect a 1k
Ω pullup resistor to DVDD for full output swing.
40
IRQ
Hardware Interrupt Output.
IRQ can be programmed to pull low when bits in the status
register 0x00 change state. Read status register 0x00 to clear
IRQ once set. Repeat faults
will have no effect on
IRQ until it is cleared by reading the I2C status register 0x00.
Connect a 10k
Ω pullup resistor to DVDD for full output swing.
41
EXTMICR
External Microphone Right-Channel Single-Ended Input. Connect a compatible high-
impedance or low-impedance (with built-in pre-amplifiers) microphone between EXTMICR
and EXTMICGND. AC-couple a microphone to EXTMICR with a series 1F capacitor.
42
EXTMICL
External Microphone Left-Channel Single-Ended Input. Connect a compatible high-
impedance or low-impedance (with built-in pre-amplifiers) microphone between EXTMICL
and EXTMICGND. AC-couple a microphone to EXTMICL with a series 1F capacitor.
43
AGND
Analog Ground
44
EXTMICGND
External Microphone Ground Sense Return. AC-couple EXTMICGND to the external jack
ground with a series 1F capacitor to reduce noise.
45
INTMICP
Internal Positive Differential Microphone Input. AC-couple a microphone to INTMICP with
a series 1F capacitor.
46
INTMICN
Internal Negative Differential Microphone Input. AC-couple a microphone to INTMICN with
a series 1F capacitor.
47
INTMICBIAS
Internal Microphone Bias. Bypass INTMICBIAS to AGND with a 1F capacitor. Provides
2.4V microphone bias for the internal differential microphone through an external 2.2k
Ω
resistor.
48
EXTMICBIASR
Right External Microphone Bias. Provides a 2.4V microphone bias for a right-channel
external microphone through an internal selectable 2.2k
Ω or 470Ω output resistor.

EP
Exposed Thermal Pad. Connect to AGND.
