Frequently Asked Questions
What output power does the TPA3139D2RGET deliver, and at what supply voltage range?
The TPA3139D2RGET delivers up to 10 W per channel in stereo from a supply voltage ranging from 3.5 V to 14.4 V, covering both single-cell lithium polymer battery packs and standard 12 V automotive power rails within a single amplifier design.
Why does the inductor-free design of the TPA3139D2RGET reduce BOM cost compared to conventional Class-D amplifiers?
Conventional Class-D amplifiers require output filter inductors, typically 10 µH to 22 µH per channel, to reconstruct the audio waveform from the PWM output. The TPA3139D2RGET eliminates these components by driving the load directly, reducing BOM by 2 to 4 inductor parts and cutting PCB area by approximately 30%.
Which package does the TPA3139D2RGET use, and how does it aid thermal management?
The TPA3139D2RGET uses a QFN package with an exposed thermal pad on the underside, enabling direct heat transfer to the PCB ground plane and reducing junction-to-board thermal resistance compared to standard SOIC or TSSOP packages, which is critical when delivering 10 W per channel continuously.
For which end-product categories is the TPA3139D2RGET a suitable stereo amplifier choice?
The TPA3139D2RGET is suitable for portable Bluetooth speakers, tablet and laptop audio subsystems, automotive head units, and docking stations, where a 3.5 V to 14.4 V supply is available and board space and component count must be minimized while achieving at least 10 W stereo audio output.
