Pin Description

LRCK

1

Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the

serial audio data line.

SDA/CDIN

(MCLKDIV2)

2

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.

SCL/CCLK

(I²S/LJ)

3

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.

AD0/CS

(TSTN)

4

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.

VA_PULLUP

5

Reference Pull-up (Input) - This pin is an input used for test purposes only and must be pulled-up to VA

using a 47 k

Ω resistor.

TSTO

6

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).

AGND

7

Analog Ground (Input) - Ground reference for the internal analog section.

TSTO

8

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).
