New Digital Audio Engine ICs Expand Intersil’s Leadership in Class-D Audio Amplifiers
Complete D2Audio® Solutions Ideal for Flat Panel TVs, PC Peripherals,
Portable Docking Stations and Many Other High-Volume Applications
Intersil to Demonstrate New Series at Consumer Electronics Show, Las Vegas, Nevada, South Hall 1, Booth 21422
MILPITAS, CA, and CES International, LAS VEGAS, NV – Jan.
7, 2010 – Intersil
Corporation (NASDAQ Global Select: ISIL),
a world leader in the design and manufacture of high-performance analog
and mixed-signal semiconductors, today introduced the latest members
of its D2Audio DAE-4P™ device series for consumer electronics products.
The D2-41051-QR, D2-41151-QR, D2-45057-QR
and D2-45157-QR are System-on-Chip (SoC) Class-D digital audio amplifiers
that provide a complete, cost-effective audio solution for Flat Panel TV
systems, PC multimedia speakers, portable device docking stations and many
other high-volume consumer products. All of the devices provide
a complete audio system, combining the industry’s most powerful and
efficient PWM audio controller with extensive integrated DSP processing
and configurable audio processing algorithms. The D2-45057-QR and
D2-45157-QR also incorporate four integrated power stages with support
for a wide range of amplifier output configurations. They provide
the industry’s broadest feature set, highest amplifier efficiency
and lowest system material cost.
The new DAE-4 products are built upon D2Audio’s renown technology, and
continue Intersil’s global leadership in high-performance audio amplifiers. They
will be demonstrated at the International CES 2010, Jan. 7-10, South Hall
1, Booth 21422.
Each device includes programmable equalizers, crossover filters, mixers, compressor/limiters
and other audio processing blocks. Both devices support 2.0, 2.1 or
bi-amp amplifier outputs, along with up to five channels of digital signal
processing. For the D2-41051-QR and D2-41151-QR, peak power output is completely
scalable with a wide range of supported full-bridge and half-bridge output
stage configurations. Performance into an 8-ohm loudspeaker can achieve
SNR > 110dB and THD+N < 0.2%. Audio signal path parameters are
programmable, and include a stereo asynchronous sample rate converter (ASRC)
along with device-specific audio enhancement processing algorithms. The
ASRC feeds a 5-channel PWM engine mapped to the four integrated power stages
as well as to the PWM output drive pins, which support additional channel
combinations of line level or headphone outputs.
Additional audio enhancement algorithms are included within specific part
number options of the devices including D2Audio SoundSuite™ WideSound™,
DeepBass™, AudioAlign™ and ClearVoice™.
The D2-41151-QR and D2-45157-QR both also support SRS® WOW/HD™ audio
enhancement technologies as options to the D2Audio SoundSuite technologies.
For the D2-45057-QR and D2-45157-QR, peak power output is 30W x 2 channels
with a full-bridge output into an 8-ohm loudspeaker, with SNR > 108dB and
THD+N < 1%.
Stereo I2S and S/PDIF digital audio input support, plus I2C and SPI serial
control interfaces, enable designers to easily integrate the D2-45057-QR and
the D2-45157-QR with existing system architectures and solutions. Signal flow
is supported by D2Audio Canvas II™ software. Audio flow and processing
options are easily modified within production environments, allowing multiple
product models to be built using a single audio system architecture.
Pricing and Availability
Intersil’s D2-41051-QR and D2-41151-QR are available now in 128-lead
LQFN packages. Prices per 1,000 pieces start at $1.78 each. The D2-45047-QR
and D2-45157-QR, which add the integrated power stages, come in 128-lead LQFN
packages, with 1000-piece prices starting at 3.06.
