Product data sheet Rev. 02 — 8 November 2007 5 of 48 NXP Semiconductors TDA8596 I2C-bus controlled 4 × 45 W power amplifier with symmetrical inputs 7. Functional description The TDA8596 is a quad BTL audio power amplifier with symmetrical inputs, made in BCDMOS technology. It contains four independent amplifier channels in BTL configuration with complementary (PMOST/NMOST) output stages (see Figure 1). The status of each amplifier channel (output offset, connected load, short circuit condition at output pins) can be read out separately via the I2C-bus. The TDA8596 is protected against overvoltage on the supply pins, short circuits at the output pins, overheating and loss-of-ground or loss-of-VP conditions. The temperature pre-warning level and the clip detection levels can be programmed via the I2C-bus. Further, the information that will be available on the diagnostic pins (i.e. DIAG or STB) can be programmed. Three different I2C-bus addresses can be selected by connecting a resistor to the ADSEL pin. In case the ADSEL pin is shorted to ground, the TDA8596 operates in legacy mode. In this mode no I2C-bus is needed and the STB pin will change from a two level pin (Standby mode and Operating mode) to a three level pin (Standby, Mute operating and Normal operating mode).
