Oki Electric today announced sample shipments of its audio LSI, ML2611, with stereo-playback capable DAC (Digital Audio Converter), 3D surround functionality, and speaker amp all incorporated in a single chip.

The LSI achieves all this in the world's smallest package size in the 16bit audio DAC with a size of 3.0mm x 3.2mm. It is equipped with an authentic acoustic sound that is used in a variety of portable equipment. Shipments of mass-production quantities of the new IC will begin in June of 2007.

Portable equipment such as mobile phones, PND(Portable Navigation Devices), and electronic dictionaries are being equipped with music playback and TV functions. However, it is very difficult to playback low frequency sounds authentically in portable equipment because of the limited space. Recognizing this situation, OKI developed the audio DAC LSI "ML2611" which can easily improve sound quality in portable equipment.

The new LSI incorporates all the functionality demanded of an audio DAC LSI, such as a stereo DAC, a stereo speaker amp, a stereo headphone amp, and the audio enhancement technology SRS WOW from SRS Labs.
