Oki will start volume shipment of a headphone amplifier LSI, the ML2650, from October 2008. This LSI enables battery-powered mobile phones to play back music with low-power consumption, which is achieved by a highly efficient D-class amplifier equipped with a 64KB SRAM that temporarily saves music data.

Oki LSI ML2650 will enable mobile device/phone manufacturers to easily extend the music playback time. In addition, with the ultra small package size at 2.54 mm x 2.70 mm, it will contribute in smaller devices as it significantly reduces the packaging space.
