The wins microelectronics Co., LTD has announced its latest launch of high performance, low power consumption, three-dimensional digital-to-analog converters (DAC) WM8918, the chip will Chelsea performance audio to include mobile phone, tablet computer, wireless headset and media players and handheld game equipment, etc. Various kinds of portable applications.

WM8918 grounding in stereo headphone amplifiers, for reference features it adopted the victories of W amplifier and an innovation dual mode charge pump structure to improve the efficiency and power consumption during playback in addition to the exchange, through to the needs of the coupling capacitors to reduce the area of the circuit board, raw material costs and improve bass response.

The games SilentSwitch ™ technology WM8918 is another feature of this kind of technology can will, heard on electricity blasting sound reduced to a minimum and shorten the software drives development time. The dynamic range of integrated controller provides compression and level control to strengthen the playback experience. When it is used to handle a chip on the figure of the microphone signal, the interface capture to ensure high quality performance record. WM8918 with European games ReTune ™ mobile five bands and quantitative equalizer, it has fully programmable coefficient, since the speaker characteristics and optimization with further enhanced playback experience.

This device only a 3.8 mW static power consumption can achieve headset playback of digital-to-analog, its typical analog-to-digital conversion signal-to-noise ratio for 96 dB. WM8918 can directly from a 1.8 V switch power supply, digital kernel can also from 1.0 V power supply in order to achieve the optimal power consumption.

The victory of the product line and microelectronics amplifier converter manager David said: "with this time a series of innovative products, and provide quick qing function through audio and low power consumption ability, WM8918 represents for the worlds leading and diversification of portable audio application of a series of an ideal solution."

Supply involved
WM8918 can now provide samples, it USES a size 4 mm * 4 mm of 32 pins QFN encapsulation.
