General description
The TFA9812 is a high-efciency Bridge Tied Load (BTL) stereo Class-D audio amplier
with a digital I2S 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 amplication. It supports
I2C control mode and Legacy mode. In Legacy mode I2C involvement is not needed
because the key features are controlled by hardware pin connections.
A continuous time output power of 2
× 12W(R
L =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 amplier stage). This minimizes the
number of external components.
