Dialog Semiconductor’s new evaluation board for its DA9034 integrated chip enables designers to quickly configure designs based on Marvell PXA3xx application processors. The board, which provides an audio- and powermanagement solution for Marvell PXA3xx-based products, is driven using a standard Windows-based graphical user interface (GUI) via a personal computer’s USB interface.
With the DA9034-EVB, developers can evaluate the technical performance of the DA9034 highly integrated audio- and power-management IC. The DA9034-EVB can also be used in conjunction with a PXA3xx processor system to develop power-management and audio-control routines, as well as verify complete designs.
The board provides a reference pc-board layout and uses components typically found in cellular-handset, portablemedia- player, and PDA designs that are optimised for low build height of less than 1.2mm, and minimum pc-board area.
Dialog’s DA9034 IC integrates more than 50 mixed signal functions on a single chip, providing regulated supplies for the PXA3xx processor, memory, and peripheral devices as well as supporting lithium-ion-battery charging, touch-screen interface, and LED driving together with voice and HiFi audio codecs.
