Overview
TDF8546 I2C-bus controlled 4  45 W best efficiency amplifier Rev.
8 — 27 September 2013 Product short data sheet 1.
General description The TDF8546 is one of a new generation of complementary quad Bridge-Tied Load (BTL) audio power amplifiers intended for automotive applications.
It has a best efficiency mode with full I2C-bus controlled diagnostics, including start-up diagnostics.
The TDF8546 can operate at a battery voltage as low as 6 V making this amplifier suitable for stop/start-car operation.
The new best efficiency principle uses a patented switch technique which reduces switching distortion.
To reduce power dissipation, the new best efficiency principle uses the audio information on all four channels instead of only the front or rear signals.
Dissipation is more than 65 % less than standard BTL when used for front and rear correlated audio signals.
Dissipation is 35 % less than standard BTL when used for uncorrelated (delayed) audio signals between front and rear.
It is 1...
