1. General descriptionThe 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 = 4 Ω)or 1 × 30 W in mono full-bridge application (RL = 8 Ω). Due to the low power dissipationthe device can be used without any external heat sink when playing music. Due to theimplementation of thermal foldback, even for high supply voltages and/or lower loadimpedances, the device remains operating with considerable music output power withoutthe need for an external heat sink.The device has two full-differential inputs driving two independent outputs. It can be usedas mono full-bridge configuration (BTL) or as stereo half-bridge configuration (SE).2.
