General description
The TDA8933B is a high-efciency class D amplier with low power dissipation.
The continuous time output power is 2
× 10 W in a stereo half-bridge application
(RL =8 )or1 × 20 W in a mono full-bridge application (RL =16 ). Due to the low power
dissipation the device can be used without any external heat sink when playing music.
Due to the implementation of Thermal Foldback (TF) the device remains operating with
considerable music output power without the need for an external heat sink, even for high
supply voltages and/or lower load impedances.
The device has two full differential inputs driving two independent outputs. It can be used
in a mono full-bridge conguration (Bridge-Tied Load (BTL)) or as stereo half-bridge
conguration (Single-Ended (SE)).
