4 x 45W Audio Power Amplifier

General description:
The TDA8595 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. Through the I2C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.
Features and benefits:
Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant)Three hardware-programmable I2C-bus addressesDrive 4  or 2  loadsSpeaker fault detectionIndependent short-circuit protection per channelLoss of ground and open VP safe (with 150 m series impedance and a supply  decoupling capacitor of 2200 F maximum)All outputs short-circuit proof to ground, supply voltage and across the loadAll pins short-circuit proof to groundTemperature-controlled gain reduction to …

4 x 45 W power amplifier

General description
The TDA8593J is a complementary quad BTL audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in Bridge Tied Load (BTL) configuration. Through the I2C-bus, the diagnostic information of each amplifier and speaker can be read separately. Both front and both rear channel amplifiers can be configured independently in line driver mode with a gain of 20 dB.
