TDA8932B

TDA8932B Class-D audio amplifier Rev. 02 — 29 March 2007 Preliminary data sheet 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 (RL = 4 Ω) or 1 × 30 W in mono 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. 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.
