# Pin Description
1 Reset (Input) - Powers down device.
2 Serial Audio Data (Input) - Input for two’s complement serial audio data.
3 Serial Clock (Input) -Serial clock for the serial audio interface.
4 Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
5 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
6 Digital Interface Format (Input) - Defines the required relationship between the Left Right
7 ^{Clock, Serial Clock and Serial Audio Data.}

response for the 44.1 kHz sample rate.
9 Positive Voltage Reference (Output) - Positive voltage reference for the internal
sampling circuits.
10 Quiescent Voltage (Output) - Filter connection for internal quiescent reference voltage.
11 Reference Ground (Input) - Ground reference for the internal sampling circuits.
12 Analog Outputs (Output) - The full scale analog output level is specified in the
15 ^{Analog Characteristics table.}
13 Analog Ground (Input)
14 Power (Input) - Positive power for the analog, digital and serial audio interface sections.
16 Mute Control (Output) - Control signal for an optional mute circuit.
