SDA/CDIN (MCLKDIV2)
Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
Serial Control Data (Input/Output) - SDA is a data I/O in I²C Mode. CDIN is the input data line for the
control port interface in SPI Mode.
MCLK Divide by 2 (Input) - Hardware Mode: Divides the MCLK by 2 prior to all internal circuitry.
Serial Control Port Clock (Input) - Serial clock for the serial control port.
Interface Format Selection (Input) - Hardware Mode: Selects between I²S & Left-Justified interface for-
mats for the ADC.
Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C Mode; CS
is the chip-select signal for SPI format.
Test In (Input) - Hardware Mode: This pin is an input used for test purposes only and should be tied to
DGND for normal operation.
Reference Pull-up (Input) - This pin is an input used for test purposes only and must be pulled-up to VA
using a 47 kΩ resistor.
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
Analog Ground (Input) - Ground reference for the internal analog section.
Test Out (Output) - This pin is an output used for test purposes only and must be left “floating” (no con-
nection external to the pin).
