-
Low Voltage Analog Power (Input) - Positive power supply for the analog section.
Positive Voltage Reference (Output) - Positive reference voltage for the internal DAC.
Reset (Input) - Optional connection for an external reset control. The device enters a powered-down
state when this pin is set low (GND) OR when the VCP supply falls below the V

mal operation.
1 or 2 V
selects 1 V
De-emphasis (Input) - Selects the standard 50 μs/15 μs digital de-emphasis filter response for 44.1 kHz
sample rates when enabled.
Digital Interface Format (Input) - Selects the serial audio interface format. Setting this pin low (GND)
selects I²S, while setting it high (VL) selects Left-Justified.
Left / Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
audio data line.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Thermal Relief Pad - This pad may be soldered to the board, however it MUST be electrically isolated
from all board connections.
