Function
—
V_DD for the digital block (Connect to +5 V.)
(Keep connections as short as possible so that potential differences between the V_DD pins do not occur.)
—
V_SS for the digital block (Connect to ground.)
(Keep connections as short as possible so that potential differences between the V_SS pins do not occur.)
— A/D converter V_DD (left channel) (Connect to +5 V.)
— A/D converter V_DD (right channel) (Connect to +5 V.)
Design the application wiring so
that potential differences do not
— A/D converter V_DD (microphone) (Connect to +5 V.)
— D/A converter V_DD (left channel) (Connect to +5 V.)
— D/A converter V_DD (right channel) (Connect to +5 V.)

pins and between the digital V_DD
group and the analog V_DD group.
— A/D converter V_SS (left channel) (Connect to ground.)
— A/D converter V_SS (right channel) (Connect to ground.)
Design the application wiring so
that potential differences do not
— A/D converter V_SS (microphone) (Connect to ground.)
— D/A converter V_SS (left channel) (Connect to ground.)
— D/A converter V_SS (right channel) (Connect to ground.)
occur between the analog V_SS
pins and between the digital V_SS
group and the analog V_SS group.
