NXP Semiconductors TDA8932B - page 1

1. General description The TD A8932B is a high efﬁciency class-D ampliﬁer with low po wer dissipation. The continuous time output pow er is 2 × 15 W in stereo half-br idge application (R L =4 Ω ) or 1 × 30 W in mono full-bridge application (R L =8 Ω ). Due to the low power dissipation the de vice can be used without any e xter nal heat si ...
