Dialog produces lower power audio codec

Written by Nick Farell


Sony gives the thumbs up
Dialog Semiconductor has released a low power DA7211 audio IC and says that it has been adopted by Sony. The outfit claims that the DA7211 is the industry's lowest power audio codec chip.  It will be seen in Sony's compact digital recorders. Sony has already launched this high end IC recorder product series.

Udo Kratz, vice president and general manager for audio and power management at Dialog said that it was a validation of the new audio technology that it was used by Sony.

"The DA7211 delivers the ultimate mix of high performance audio with ultra low power consumption allowing Sony to extend the battery lifetime and playback time of their new series of IC Recorders. With our first audio products only released in the last 12 months, we are proud of this early success with Sony,"  Kratz said.

Sony's latest IC recorders incorporate Sony's proprietary and advanced S-Mic recording technology with dual A/D converters included for wider dynamic range and improved signal to noise ratio (SNR). The DA7211 comes with a simple interface and general purpose filter, which enables manufacturers to optimise the output signal for small on board speakers and enclosures, delivering even complex 3D spatial effects. The 3x3mm chip has the lowest quiescent power consumption in its class.
