TDF8551J Datasheet (NXP Semiconductors) - I2C-bus controlled 4 x 45W power amplifier

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
