Soon you’ll be able to playback the music on your cell phone for a longer time, thanks to a new technology used in the headphone amplifier LSI called ML2650. It will be provided by Oki Electric Industry, a top telecommunication solutions manufacturer from Japan.

This new module measuring 2.54 x 2.70 mm will start shipping next month bringing a D-class amplifier with 64KB SRAM for saving music temporary, enabling lower power consumption, which leads to longer battery life. The Static Random Access Memory is opposed to the Dynamic Random Access Memory, and doesn’t need to be refreshed from time to time, but is lost when not powered.

Not only cell phones will benefit from its capabilities, but also the other portable digital devices using music playback. As all these need higher and higher central processing unit performance, Oki came up with the easiest solution – moving processed music data onto the Random Access Memory, releasing the processor from this demanding task.

Hiroshi Enomoto, President of Silicon Solutions Company at OKI explains: “OKI developed the ML2650, which includes a D-class headphone amplifier to connect with the external CPU, a 64KB SRAM, and a 16 bit stereo DA converter, all on a single chip that will help to reduce load from the CPU. This LSI 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.”
