Preliminary data sheet

1. General description

The TDA8932 is a high efficiency class-D amplifier with low power dissipation.

The typical output power is 2 × 15 W in stereo half-bridge application (RL = 4 Ω) or

1 × 30 W typical in full-bridge application (RL = 8 Ω). Due to the low power dissipation the

device can be used without any external heat sink when playing music. If proper cooling

via the printed-circuit board is implemented, a continuous output power of 2 × 15 W is

feasible. 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).
