# Pin Description
1 Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio inter-
face. Refer to the Recommended Operating Conditions for appropriate voltages. Applies to pins 2-7.
2 Serial Audio Data Input (Input) - Input for two’s complement serial audio data. SDIN1 corresponds to
3 ^{AOUT1x, SDIN2 corresponds to AOUT2x and SDIN3 corresponds to AOUT3x.}
4
5 Serial Clock (Input) - Serial clock for the serial audio interface.
6 Left / Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
audio data line. The frequency of the left/right clock must be at the audio sample rate, Fs.
7 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters. Table 6 illustrates
several standard audio sample rates and the required master clock frequency.
8 Digital Power (Input) - Positive power supply for the digital section. Refer to the Recommended Operat-
ing Conditions for appropriate voltages.
9 Ground (Input) - Ground reference. Should be connected to analog ground.
21
10 Reset (Input) - The device enters a low power mode and all internal registers are reset to their default
settings when low. The control port cannot be accessed when Reset is low.
14 Control Port Interface Power (Input) - Determines the required signal level for the control port and pro-
vides power for bidirectional control port pins. Refer to the Recommended Operating Conditions for
appropriate voltages. Applies to pins 10-13 and 15.
16 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Requires the capacitive decoupling to GND as shown in the Typical Connection Diagram.
