TDA8589BJ I2C Bus Controlled 4 x 45 Watt Power Amplifier and Multiple Voltage Regulator

Amplifiers The TDA8589 has a complementary quad audio power amplifier that uses BCDMOS technology. It contains four amplifiers configured in Bridge Tied Load (BTL) to drive speakers for front and rear left and right channels. The I2C-bus allows diagnostic information of each amplifier and its speaker to be read separately. Both front and both rear channel amp.
