TDF8553J I2C-bus controlled 4 X 50 Watt power amplifier and multiple voltage regulator

1.1 Ampliﬁers The TDF8553 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.
