Cellular-Processor Audio/Power Chip Rings True For GSM/GPRS Handsets

The DA9010 represents a highly integrated audio- and power-management solution for the Intel PXA800F cellular processor for GSM/GPRS phones with enhanced application capabilities. On one chip, it provides the key power-manage bit stereo digital-to-analog converter (DAC); and 16 headphone drivers. Due to the product's Dialog Smart Mirror technology, the LDOs can use an advanced compensation and biasing technique compared to conventional regulators. The regulators can bias themselves proportionally to the output current requirement without needing to switch between different operating modes. This low quiescent current consumption eliminates the need for a low-power mode, simplifying the power control design of the phone handset. On the audio side, the DA9010 enables CD-quality sound with its 24-bit stereo DAC that uses multibit modulator technology. The DA9010 is available now in a 121-pin BGA package. The DA9010 audio/power chip costs about $2.60 each in high-volume lots.
