1. General description

The TDA8932B is a high efﬁciency class-D ampliﬁer with low power dissipation.

The continuous time output power is 2 × 15 W in stereo half-bridge application (R

L

=4Ω)

or 1 × 30 W in mono full-bridge application (R

L

=8Ω). 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 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).

2. Features

n Operating voltage from 10 V to 36 V asymmetrical or ±5 V to ±18 V symmetrical

n Mono-bridged tied load (full-bridge) or stereo single-ended (half-bridge) application

n Application without heatsink using thermally enhanced small outline package

n High efﬁciency and low-power dissipation

n Thermally protected and thermal foldback

n Current limiting to avoid audio holes

n Full short-circuit proof across load and to supply lines (using advanced current

protection)

n Switchable internal or external oscillator (master-slave setting)

n No pop noise

n Full-differential inputs

3. Applications

n Flat panel television sets

n Flat panel monitor sets

n Multimedia systems

n Wireless speakers

n Mini and micro systems

n Home sound sets
