TDA8932B
Class-D audio amplifier
Rev. 03 — 21 June 2007
The TDA8932B is a high efficiency class-D amplifier with low power dissipation.
The continuous time output power is 2
or 1
30 W in mono full-bridge application (R
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 remains operating 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
as mono full-bridge configuration (BTL) or as stereo half-bridge configuration (SE).
