Transcription of TDA8932B Class-D audio amplifier
{{id}} {{{paragraph}}}
1. General descriptionThe TDA8932B is a high efficiency Class-D amplifier with low power continuous time output power is 2 15 W in stereo half-bridge application (RL=4 )or 1 30 W in mono full-bridge application (RL=8 ). 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 continues to operate with considerable music output powerwithout the need for an external heat device has two full-differential inputs driving two independent outputs. It can be usedin a mono full-bridge configuration (BTL) or in a stereo half-bridge configuration (SE).
