TDF8551J I2C-bus controlled 4 x 45W power amplifier

1.1 Ampliﬁers The TDF8551J has a complementary quad audio power ampliﬁer that uses BCDMOS technology. It contains four ampliﬁers conﬁgured in Bridge-Tied Load (BTL) to drive four speakers: two front and two rear channels. The I2C-bus enables diagnostic information of each ampliﬁer and its speaker to.
