Description

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 to be read separately.Both front and both rear channel ampliﬁers can be conﬁgured independently in line driver mode with a gain of 20 dB (differential output) or ampliﬁer mode with a gain of 26 dB (

Features

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 4 % N Programmable thermal protection pre-warning N Independent short-circuit protection per 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 ground,.
