DIALOG SEMICONDUCTOR'S NEW AUDIO SPEAKER DRIVER IC BRINGS 3X POWER OUTPUT
TO ULTRABOOKS
Dialog's new DA7202 speaker driver IC is designed to deliver improved sound
levels and efficiency for dual cell battery powered portable devices,
without compromising sound quality
Kirchheim/Teck, Germany, 5 November 2013 - Dialog Semiconductor plc (FWB:
DLG), a provider of highly integrated power management, audio, AC/DC, solid
state lighting and short-range wireless technologies, announced today the
first product in its new range of Class D audio products, the DA7202. This
powerful, highly efficient low EMI Class D speaker driver provides greater
power output and improved efficiency levels for UltrabooksTM, tablets and
speaker accessories powered by a dual cell battery pack. Designed with a
small footprint, the DA7202 helps keep devices, such as the increasingly
popular Ultrabook as light and compact as possible for the consumer.
The DA7202 is available in a 9 bump WLCSP package, 0.5mm pitch that enables
low cost printed circuit board (PCB) technology. The increased power output
does not compromise the speaker audio quality and is designed to provide
90dB Total Harmonic Distortion plus noise (THD+N) and 100dB Signal to Noise
ratio. This allows the end users to experience Hi-Fi quality audio, from
ground shaking lows to delicate highs.
Historically, most mobile computing devices have used a CODEC with an
integrated Class D amplifier, providing a speaker driver output limited to
1Watt (W). Using a dual cell Class D amplifier significantly improves the
power output of the device, driving up to 3.5Wrms, which equates to a 3.5x
increase of power into the speaker. In addition to a higher power output,
this audio architecture maintains better efficiency, as having a direct
connection from the battery to Class D amp, eliminates DC-DC power loss.
Additional benefits include:
- Robust short circuit and thermal overload protection to prevent device
damage during a fault condition;
- Differential audio inputs for improved resistance to external noise;
and
- Low Electromagnetic Interference (EMI) by using spread spectrum
modulation. This reduces interference in nearby components, thereby
simplifying system design.
'The DA7202 perfectly addresses the requirements of the Ultrabook and other
portable device markets powered by a dual cell battery pack,' said Udo
Kratz, Senior Vice President and General Manager, Mobile Systems Business
Group at Dialog. 'Traditional amplifiers integrated in a CODEC are limited
in the power they can supply, but our new external Class D amplifier offers
a powerful and more efficient solution for the expanding dual cell market.
Within Dialog, we are constantly developing power saving technologies,
and this focus is enabling fresh, exciting and enhanced user experiences
for the portable market,' added Kratz.?ENDS?Company Contact:
