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. Features
n High efficiency
n Application without heat sink using thermally enhanced small outline package
n Operating voltage from 10 V to 36 V asymmetrical or ± 5 V to ± 18 V symmetrical
n Thermally protected
n Thermal foldback
n Current limiting to avoid audio holes
n Full short circuit proof to supply lines (using advanced current protection)
n Switchable internal / external oscillator (master-slave setting)
n No pop noise
n Low power dissipation
n Mono bridge-tied load (full bridge) or stereo single-ended (half bridge) application
n Full differential inputs
3. Applications
n Flat panel television sets
n Flat panel monitor sets
n Multimedia systems
n Wireless speakers
n Mini/micro systems
n Home sound sets
