PWRUPSEL 20 I Selects the power-up default mode
REXT 6 I/O Internal reference current setting terminal. This terminal uses a precision 100-kΩ resistor and no filtering
capacitors.
RESET 21 I Active low reset
SCL 12 I I
2
C-bus serial clock. This input is used to synchronize the data transfer from and to the PCM codec.
SDA 11 I/O I
2
C-bus serial address/data input/output. This is a bidirectional terminal used to transfer register control
addresses and data into and out of the codec. It is an open
-drain terminal and therefore requires a pullup resistor
to V
DD
(typical 10 kΩ for 100 kHz).

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
