7. Functional description
The TDA8595 is a complementary quad BTL audio power amplifier made in BCDMOS
technology. It contains four independent amplifiers in BTL configuration (see Figure 1).
Through the I2C-bus, the diagnostic functions of temperature level and clip level are fully
programmable and the information to be shown on the two diagnostic pins can be
selected. The status of each amplifier (output offset, load or no load, short-circuit or
speaker incorrectly connected) can be read separately. The TDA8595 is protected against
overvoltage, short-circuit, over-temperature, open ground and open VP connections.
Three different I2C-bus addresses are selected with an external resistor connected to the
ADSEL pin. If the ADSEL pin is short-circuit to ground, the TDA8595 operates in legacy
mode. In this mode, no I2C-bus is needed and the function of the STB pin will change from
two level (Standby mode and On mode) to a three level pin (Standby mode, On mode and
mute).
