DDS2
Secondary Digital Audio Interface Power-Supply Input. Bypass to DGND with a 1µF
capacitor.
13MHz/26MHz Master Clock Input
Transducer/Vibrator Output. Open-drain output programmable to control a vibrator motor
or a transducer. Connect a 1kΩ pullup resistor to DV
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 I
Connect a 10kΩ pullup resistor to DV
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 1µF capacitor.
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 1µF capacitor.
Analog Ground
External Microphone Ground Sense Return. AC-couple EXTMICGND to the external jack
ground with a series 1µF capacitor to reduce noise.
Internal Positive Differential Microphone Input. AC-couple a microphone to INTMICP with
a series 1µF capacitor.
Internal Negative Differential Microphone Input. AC-couple a microphone to INTMICN with
a series 1µF capacitor.
Internal Microphone Bias. Bypass INTMICBIAS to AGND with a 1µF capacitor. Provides
2.4V microphone bias for the internal differential microphone through an external 2.2kΩ
resistor.
Right External Microphone Bias. Provides a 2.4V microphone bias for a right-channel
external microphone through an internal selectable 2.2kΩ or 470Ω output resistor.
Exposed Thermal Pad. Connect to AGND.
