Pin Description
Control Interface Power (Input) - Positive power for the hardware/software control interface
Regulator Voltage (Output) - Filter connection for internal voltage regulator
Recovered Master Clock (Output) - Outputs a master clock derived from LRCK
Serial Audio Interface Power (Input) - Positive power for the serial audio interface
Serial Clock (Input) - Serial bit-clock for the serial audio interface
Serial Audio Data Input (Input) - Input for two’s complement serial audio data
Left/Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
audio data line
Test Output - These pins need to be floating and not connected to any trace or plane.
Differential Analog Outputs (Output) - The full scale differential output level is specified in
log Characteristics - Commercial (-CZZ)” on page
Positive Voltage Reference (Output) - Positive reference voltage for the internal DAC
Analog Power (Input) - Positive power supply for the analog section
Quiescent Voltage (Output) - Filter connection for internal quiescent voltage
