Pin Description
1 Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
2 De-Emphasis/External Serial Clock Input (Input) - used for de-emphasis filter control or external serial
clock input.
3 Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial audio
data line.
4 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
5 Quiescent Voltage (Output) - Filter connection for internal quiescent voltage.
6 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling
circuits.
7 Left Channel Analog Output (Output) - The full scale analog output level is specified in the Analog Char-
acteristics specification table.
8 Ground (Input) - ground reference.
9 Analog Power (Input) - Positive power for the analog and digital sections.
10 Right Channel Analog Output (Output) - The full scale analog output level is specified in the Analog
Characteristics specification table.
