TDF8541: I²C-bus controlled 4 x 45 W power amplifier
The TDF8541 is one of a new generation of complementary quad Bridge-Tied Load (BTL) audio power amplifiers intended for automotive applications. It has full I²C-bus controlled diagnostics, including start-up diagnostics. The TDF8541 can operate at a battery voltage as low as 6 V making this amplifier suitable for stop/start-car operation.
The amplifier uses a complementary DMOS output stage in a Silicon-On-Insulator (SOI)- based BCD process. The DMOS output stage ensures a high- power output signal with perfect sound quality. The SOI-based BCD process ensures a robust amplifier, where latch-up cannot occur, with good separation between the four independent channels, with every component isolated and without substrate currents.
