Klasse D forstærker med integreret boost konverter

Texas Instruments introducerer klasse-D forstærker med integreret boost-konverter, hvilket gør det muligt at booste lydstyrken med 36 procent (in english).

Texas Instruments (TI) introduces a 2-W mono Class-D audio amplifier with integrated boost converter, which delivers 36 percent louder audio than competitive devices, consistent across the entire Li-Ion battery range.

The highly efficient TPA2015D1 allows more than twice the battery life compared to the nearest competing amplifier and is available in a compact 2-mm x 2-mm WCSP package for space-constrained applications including smart phones, notebooks, portable navigation devices, portable docking station and portable DVD players.


In addition, the amplifier incorporates battery monitoring automatic gain control (AGC) and SpeakerGuard technology to prevent early shutdown at low battery voltages and prevents clipping, which protects speakers.  

The TPA2015D1 is available today in a 2-mm x 2-mm, 0.5-mm pitch 16-ball WCSP for $1.10 in 1,000-unit quantities. The TLV320AIC3254 audio codec with miniDSP and TPA6141A2 Class-G audio headphone amp are also available to complete the audio signal chain.
