SHENZHEN, China, June 14, 2017 /PRNewswire/ -- Qualcomm
Technologies International, Ltd., a subsidiary of Qualcomm
Incorporated (NASDAQ: QCOM), on the eve of its voice and music
developer conference in Shenzhen,
today introduced its next generation Qualcomm® DDFA™ audio
amplifier technology for high-resolution audio devices including
wireless speakers, soundbars, networked audio and headphone
amplifiers.
Traditional class D amplifiers, although power efficient,
typically don't deliver the audio quality of traditional linear
amplifiers. DDFA's all-digital PWM (pulse width modulator) and
patented closed-loop architecture compensate for nonlinearities of
power supplies and output stages and are designed to deliver much
higher fidelity audio and design flexibility while retaining the
advantages of class D amplifiers.
Next generation DDFA will be available on the CSRA6620 SoC, a
highly integrated platform which includes a DDFA controller with
eight channel inputs, two channel outputs, microcontroller and
configurable audio processor, all of which help OEMs to integrate
best-in-class amplifier performance in a lower complexity, more
cost effective way than was previously possible. The new CSRA6620
platform is available as a 9mm x 9mm QFN package making it ideal
for smaller form factor products and bringing extremely high
performance audio to many new categories and applications.
"Delivering superior sound experiences is a major focus of our
industry leading audio technologists, and with Qualcomm DDFA we are
bringing best in class amplifier technology to a new generation of
audio devices. This will help customers looking to meet the demand
for high quality audio from increasingly audio-savvy consumers,"
said Anthony Murray, senior vice
president and general manager, voice and music, Qualcomm
Technologies International, Ltd. "DDFA technology has been proven
by a number of very premium audio manufacturers, and this new
release means that many more OEMs can easily integrate
high-performance amplifier capability into products without
significantly increasing integration time or cost. We also offer
all the necessary support and tuning tools to help our customers to
deliver their own signature sound."
Shinichi Yamauchi, Denon Sound
Manager said, "At Denon we are committed to delivering the best
audio quality possible. We have chosen Qualcomm DDFA technology
because it is the only class D technology that can deliver the high
level of performance we are looking for."
Key CSRA6620 performance metrics:
- SNR and dynamic range up to 113 dB (A-wt, 20Hz to 20Khz)
- THD+N < 0.005% (20Hz to 20Khz)
- Noise floor modulation <2dB (-60dBFS to 0dBFS)
- Residual noise : 35μVrms @ 1Khz
- Support for 384Khz and DSD64/128 inputs
