Dialog Semiconductor unveils standalone Class-G audio codec with
industry-leading 2.5mW consumption
Tiny 3x3mm footprint features a programmable filter engine to optimise
headphone and speaker response to be demonstrated this week at the 127th
AES Convention in New York
Kirchheim/Teck, 8th October 2009 - Dialog Semiconductor plc (FWB: DLG), a
leading provider of highly integrated innovative Power Management
Semiconductor solutions, today announced the DA7210, a high performance
Class G audio codec that incorporates the industry's first onboard general
purpose filter (GPF). The filter is a configurable signal processing
engine that enables fine-tuning and optimisation of the output signal for
small speakers and enclosures. Its integration saves design time, board
space and cost.
The DA7210 includes a true-ground, capacitor-less headphone driver which
helps improve bass response. It features the industry's lowest quiescent
headphone playback power consumption at 2.5mW and only 5mW operating power
under listening conditions. This combination extends battery life
significantly in low power digital portable audio products such as smart
phones, personal media players, multimedia handsets and personal navigation
DA7210 delivers 40mW output into 16 Ohm headphones. It uses output signal
envelope tracking across multiple pre-defined levels for true ground
operation and features an integrated PLL for sample rate flexibility. The
device operates down to 1.8V simplifying digital processor interfacing.
The GPF enables onboard signal tailoring and performance tuning without
degradation or loss of sound quality, and removes the need for a dedicated
'With the introduction of the DA7210 Dialog has significantly eased the
portable audio design process for portable applications without sacrificing
sound quality. By incorporating a GPF on the codec we have not only
offloaded these tasks from the processor, we have significantly lowered the
cost and power consumption when compared with traditional solutions that
require an external DSP,' said Mark Jacob, director of marketing at Dialog
Semiconductor. 'The DA7210 delivers the ultimate mix of high performance
audio, ultra low power consumption, and reduced system design complexity.'
Traditional low power audio codecs rely on sophisticated external DSP
devices running proprietary algorithms for audio enhancement or more
complex noise suppression functions. Dialog's integral GPF comprises eight
programmable bi-quad sections delivering flexible DSP processing
functionality within the codec device itself. The audio signal sent to the
speakers can be tailored for optimum response without modifying the host
processor software. In addition to output tailoring, the GPF can be used
for equalisation and notch filtering, for example, enabling the noise from
camera zoom motors to be attenuated and other audio enhancements including
3D spatial effects.
The DA7210 features stereo playback/record, high signal-to-noise ratio
(100dB DAC and 95dB ADC), a 24-bit sample rate up to 96kHz and an integral
I2C/PCM interface. It includes differential stereo microphone amplifiers.
It is packaged in a 0.4mm-pitch QFN or CSP package with a 0.5mm-pitch CSP
option (named the DA7211).
Engineering samples will be available from November 2009 with volume
production delivery from Q1 of 2010.
