2.1 General features
The TFA9812 is a high-efficiency Bridge Tied Load (BTL) stereo Class-D audio amplifier
with a digital I
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
because the key features are controlled by hardware pin connections.
A continuous time output power of 2
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.
