STMicroelectronics TDA8932T

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).
