1 / 47 page 1. General description The TDA8933 is a high efficiency class-D amplifier with low power dissipation. The continuous time output power is 2 × 10 W in a stereo half bridge application (RL =8 Ω)or1 × 20 W in a mono full bridge application (RL =16 Ω). 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), even for high supply voltages and/or lower load impedances, the device will continue to operate with considerable music output power without the need for an external heat sink. The device has two full differential inputs driving two independent outputs. It can be used in a mono full bridge configuration (Bridge-Tied Load (BTL)) or a stereo half bridge configuration (Single-Ended (SE)). 2.
