BTL stereo Class-D audio amplifier with I2S input  
Rev. 02 — 22 January 2009  
Preliminary data sheet  
1. General description  
The TFA9812 is a high-efficiency Bridge Tied Load (BTL) stereo Class-D audio amplifier  
with a digital I S audio input. It is available in a HVQFN48 package with exposed die  
paddle. The exposed die paddle technology enhances the thermal and electrical  
performances of the device.  
The TFA9812 features digital sound processing and audio power amplification. It supports  
I C control mode and Legacy mode. In Legacy mode I C involvement is not needed  
because the key features are controlled by hardware pin connections.  
A continuous time output power of 2 × 12 W (RL = 8, VDDP = 15 V) is supported without  
an external heat sink. Due to the implementation of a programmable thermal foldback  
even for high supply voltages, higher ambient temperatures, and/or lower load  
impedances, the device operates without sound interrupting behavior.  
TFA9812 is designed in such a way that it starts up easily (no special power-up sequence  
required). It features various soft and hard impact protection mechanisms to ensure an  
application that is both user friendly and robust.  
A modulation technique is applied for the TFA9812, which supports common mode choke  
approach (1 common mode choke only per BTL amplifier stage). This minimizes the  
number of external components.
