I/O
Internal 10
-
mA reference current setting pin – use precision 100-k resistor and no filtering capacitors
SCL
18
H4
I
I2C-bus serial clock – this input is used to synchronize the data transfer from and to the CODEC
SDA
17
H3
I/O
I2C-bus serial address/data input/output – this is a bidirectional pin used to transfer register control
addresses and data into and out of the codec. It is an open
-drain terminal and therefore requires a
pull-up resistor to VDD (typical 10 k for 100 kHz)
VSS
12
G1
I
Ground return for all internal circuits. To minimize noise sources, ground connections to each device
must meet as close as possible to the VSS pin.
