6 / 17 page TDA7575PD 6/17 I2C BUS INTERFACE Data transmission from microprocessor to the TDA7575PD and viceversa takes place through the 2 wires I2C BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage must be connected). Data Validity As shown by fig. 1, the data on the SDA line must be stable during the high period of the clock. The HIGH and LOW state of the data line can only change when the clock signal on the SCL line is LOW. Start and Stop Conditions As shown by fig. 2 a start condition is a HIGH to LOW transition of the SDA line while SCL is HIGH. The stop condition is a LOW to HIGH transition of the SDA line while SCL is HIGH. Byte Format Every byte transferred to the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit. The MSB is transferred first. Acknowledge The transmitter* puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see fig.3). The receiver** the acknowledges has to pull-down (LOW) the SDA line during the acknowledge clock pulse, so that the SDAline is stable LOW during this clock pulse. * Transmitter =master ( µP) when it writes an address to the TDA7575PD = slave (TDA7575PD) when the µP reads a data byte from TDA7575PD ** Receiver = slave (TDA7575PD) when the µP writes an address to the TDA7575PD =master ( µP) when it reads a data byte from TDA7575PD VO Offset Detection Power Amplifier in play condition AC Input signals = 0 ±1.5 ±2 ±2.5 V I2C BUS INTERFACE fSCL Clock Frequency 400 KHz VIL Input Low Voltage 1.5 V VIH Input High Voltage 2.3 V Symbol Parameter Test Condition Min.
