1.1 Ampliﬁers The TDF8551J has a plementary 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 be read separately.

I Ampliﬁers N I2C-bus control N Can drive a 2 Ω load with a battery voltage of up to 16 V and a 4 Ω load with a battery voltage of up to 18 V N DC load detection: open, short and present N AC load (tweeter) detection N Programmable clip detect; 1 % or 3 % N Programmable thermal protection pre-warning N Independent short-circuit protection for each channel N Selectable line driver (20 dB) and ampliﬁer mode (26 dB) N Loss-of-ground and open VP safe N All outputs protected from short-circuit to gro.
