Power management chip is sound handset choice
A combined audio and power management IC launched last year by Dialog Semiconductor features in a new mobile phone handset claimed to be the first on the market based on an Intel cellular processor.
The IC is based on and supersedes the DA9010, launched in February 2003.
The DA9011 features the same high level of integration as the previous generation of this IC.
In addition to the new software and hardware MIDI support, the DA9011 incorporates Dialog Semiconductor's unique Smart Mirror technology, and provides, on a single chip, 12 high-performance low dropout (LDO) regulators, high efficiency DC/DC buck convertors, LED and vibrator drivers, 24bit stereo DAC and 16ohm headphone drivers.
Smart Mirror uses advanced compensation and biasing techniques compared to conventional regulators, to help minimise quiescent current consumption and optimise power supply rejection (PSRR) performance.
The DA9011 is available now as a standard part, in a 121-pin, 8 x 8mm BGA package.
