2.7W mono Class D for battery-powered speakers
The TPA2013D1RGPR: Mono output suits portable Bluetooth speakers, voice assistants, and single-speaker IoT audio alerts where PCB real estate is tight.
Supply range and input topology
Differential inputs reject common-mode noise from the ground loop between a Bluetooth module and the amplifier — a real concern when the antenna return current shares the same ground plane. On-chip short-circuit and thermal protection means the output stage folds back before the speaker coil cooks or the QFN package desolders itself.
