NAME
FUNCTION
1
A2
DGND
Digital Ground
2
B3
SCL
I2C Serial-Clock Input. Connect a pullup resistor to a 1.7V to 3.3V supply.
3
A3
SDA
I2C Serial-Data Input/Output. Connect a pullup resistor to a 1.7V to 3.3V supply.
4C3
IRQ
Hardware Interrupt Output. IRQ can be programmed to pull low when bits in
status register 0x00 are set. Read status register 0x00 to clear IRQ once set.
Repeat faults have no effect on IRQ until it is cleared by reading register 0x00.
Connect a 10k
pullup resistor to a 1.7V to 3.3V supply.
5
A4
AVDD
Analog Power Supply. Bypass to AGND with a 1F capacitor.
6
B4
REF
Converter Reference. Bypass to AGND with a 2.2F capacitor (1.23V nominal).
7
A5
PREG
Positive Internal Regulated Supply. Bypass to AGND with a 1F capacitor (1.6V
nominal).
8
B5
REG
PREG/2 Voltage Reference. Bypass to AGND with a 1F capacitor (0.8V nominal).
9
A6
AGND
Analog Ground
10
B6
MICBIAS
Low-Noise Microphone Bias. Connect a 2.2k
to 470 resistor to the positive
output of a microphone (1.525V nominal). Bypass to AGND with a 1F capacitor.
11
C5
MICLN/
DIGMICCLK
Left Negative Differential Microphone Input or Digital Microphone Clock Output.
For analog microphones, AC-couple to the negative output of a microphone with a
1F capacitor. For digital microphones, connect to the clock input of the
microphone.
12
C6
MICLP/
DIGMICDATA
Left Positive Differential Microphone Input or Digital Microphone Data Input. For
analog microphones, AC-couple to the positive output of a microphone with a 1F
capacitor. For digital microphones, connect to the data output of the
microphone(s). Up to two digital microphones can be connected.
13
C4
MICRP
Right Positive Differential Microphone Input. AC-couple to the positive output of a
microphone with a 1F capacitor.
14
D6
MICRN
Right Negative Differential Microphone Input. AC-couple to the negative output of
a microphone with a 1F capacitor.
15
D5
LINL
Left-Line Input. AC-couple analog audio signal to LINL with a 1F capacitor.
16
E6
LINR
Right-Line Input. AC-couple analog audio signal to LINR with a 1F capacitor.
17
D4
JACKSNS/AUX
Jack Sense or Auxiliary ADC Input. When configured for jack detection, JACKSNS
detects the presence or absence of a jack. See the Mode Configuration section
for details. When configured as an auxiliary ADC input, AUX is used to measure
DC voltages.
18
E5
PGND
Headphone Power Ground
19
D3
ROUTP
Positive Right-Channel Headphone Output. Connect directly to the load in
differential and capacitorless mode. AC-couple to the load in single-ended mode.
20
E4
ROUTN
Negative Right-Channel Headphone Output. Inverting output in differential mode.
Leave unconnected in capacitorless and fast turn-on single-ended mode. Bypass
with a 1F capacitor to AGND in clickless, single-ended mode.
21
D2
LOUTN
Negative Left-Channel Headphone Output. Noninverting output in differential
mode. Common headphone return in capacitorless mode. Leave unconnected in
fast turn-on single-ended mode. Bypass with a 1F capacitor to AGND in clickless
single-ended mode.
