Address selection and I2C disable

TDA7567PD

When the ADSEL/I2CDIS pin is left open the I2C bus is disabled and the device can be

controlled by the STBY/MUTE pin.

In this status (no - I2C bus) the CK pin enables the HIGH-EFFICIENCY MODE (0 = STD

MODE; 1 = HE MODE) and the DATA pin sets the gain (0 = 26 dB; 1 = 16 dB).

When the ADSEL/I2CDIS pin is connected to GND the I2C bus is active with address

<1101100-1>.

To select the other I2C address a resistor must be connected to ADSEL/I2CDIS pin as

following:

0<R<~10kΩ: I2C bus active with address <1101100x>

~25k<R< 35kΩ: I2C bus active with address <1101101x>

R>60k: Legacy mode only
