OKI: headphone amplifier LSI to handle music for longer battery life
OKI Electric Industry, senior player in this industry, will ship its latest headphone amplifier LSI, named ML2650, starting this October. Founded in 1881, OKI is Japan’s first telecommunication manufacturer. This LSI will enable battery-powered mobile phones to play back music with low-power consumption. Not only for mobile phone, this chip can also be used in mp3 player for longer battery life.
How this chip does it? OKI claimed, one way to control power consumption is by pacing operation of the CPU, which is a method to forward music data processed on the CPU to RAM within the device, and put the CPU to rest or standby.
Thus, OKI built 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, said Hiroshi Enomoto, President of Silicon Solutions Company at OKI.
The chip is claimed to significantly reduce battery usage. How significant? Well, the site doesn’t reveal any statistical data how much power can be reduced or how many days can be extended. Let’s wait for more proven review.
