Music playback on mobile phones and other portable devices require a lot of CPU power which in turn drains the battery much faster than usual. OKI from Japan have found a solution to this by developing a headphone amplifier LSI dubbed as ML2650. This miniature chip embeds an efficient D-class amplifier equipped with a 64KB SRAM and 16 bit stereo DA converter. The D-class amplifier connects with the CPU and the SRAM temporarily saves music data onto its memory taking some load off from the CPU to perform its action. The chip which measures just 2.54 mm x 2.70 mm is small enough to fit in most of today’s portable gadgets.
The sample is available to all manufacturers while the mass shipment will start from next month.
