Class-D audio ampliï¬er

Rev. 04 â 18 December 2008

Product data sheet

1. General description

The TDA8932B is a high efï¬ciency class-D ampliï¬er with low power dissipation.

The continuous time output power is 2 Ã 15 W in stereo half-bridge application (RL = 4 â¦)

or 1 Ã 30 W in mono full-bridge application (RL = 8 â¦). 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, even for high supply voltages and/or lower load

impedances, the device continues 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 conï¬guration (BTL) or in a stereo half-bridge conï¬guration (SE).
