Dialog aims at high performance audio market
Looking to address the need for low power, high performance audio devices in portable products, Dialog Semiconductor has launched the DA7210. The Class G audio codec incorporates what is said to be the industry's first onboard general purpose filter (GPF). This configurable signal processing engine enables fine tuning and optimisation of the output signal for small speakers and enclosures and its integration is said to save design time, board space and cost.
"Dialog has eased the portable audio design process without sacrificing sound quality," said Mark Jacob, Dialog's director of marketing. "By incorporating a GPF on the codec, we have not only offloaded these tasks from the processor, we have also lowered cost and power consumption significantly when compared with traditional solutions that require an external dsp."
The DA7210 has a quiescent headphone playback power consumption of 2.5mW and draws 5mW under listening conditions. It delivers 40mW output into 16? headphones and features an integrated PLL for sample rate flexibility.
Packaged in a 0.4mm pitch QFN or 0.5mm pitch CSP, engineering samples will be available from November and volume is planned for Q1 2010.
