TDA7575PD

SOFTWARE SPECIFICATIONS

All the functions of the TDA7575PD are activated by I2C interface.

The bit 0 of the "ADDRESS BYTE" defines if the next bytes are write instruction (from

µP to TDA7575PD) or

read instruction (from TDA7575PD to

µP).

ADDRESS SELECTION

If R/W = 0, the

µP sends 2 "Instruction Bytes": IB1 and IB2.

IB1

IB2

R/W

Diagnostic enable (D6 = 1)

Diagnostic defeat (D6 = 0)

Offset Detection enable (D5 = 1)

Offset Detection defeat (D5 = 0)

Gain = 26dB (D4 = 0)

Gain = 12dB (D4 = 1)

Mute (D2 = 0)

Unmute (D2 = 1)

CD 2% (D0 = 0)

CD 10% (D0 = 1)

used for testing

Stand-by on - Amplifier not working - (D4 = 0)
