Dialog Semiconductor Plc has updated its integrated power management and audio solution for the Intel PXA800F cellular processor.

The DA9011 GSM/GPRS audio and power controller now supports both software and hardware MIDI solutions, an essential feature required for versatile ringtone and gaming functions in mobile phone handset designs. The IC is based on and supersedes the DA9010, launched in February 2003.

According to the company, the DA9011 features the same high level of integration as the previous generation. In addition to the new software and hardware MIDI support, the new product incorporates the company's Smart Mirror technology, and provides, on a single chip, 12 high-performance low dropout (LDO) regulators, high efficiency dc-dc buck converters, LED and vibrator drivers and 24-bit stereo DAC.

The Smart Mirror technology uses advanced compensation and biasing techniques compared to conventional regulators, to help minimize quiescent current consumption and optimize power supply rejection (PSRR) performance.

The DA9011 is available as a standard part, in a 121 pin 8-by-8mm BGA package.
