深圳市合冠电子提供wm8741库存，wm8741参考设计规范，wm8741技术资料，wm8741规格文档 wm8741: high performance stereo dac wm8741简介：wm8741描述 the wm8741 is a very high performance stereo dac designed for audio applications such asprofessional recording systems, a/v receivers and high specification cd, dvd and home theatre systems. the device supports pcm data input word lengths from 16 to 32-bits and sampling rates up to192khz. the wm8741 also supports dsd bit-stream data format, in both direct dsd and pcm-converted dsd modes. the wm8741 includes fine resolution volume and soft mute control, digital de-emphasis anda range of advanced digital filter responses, followed by a digital interpolation filter, multi-bit sigma delta modulator and stereo dac. wolfson’s patented architecture optimises the linearity ofthe dac and provides maximum insensitivity to clock jitter. the digital filters include several selectable roll-off and performance characteristics. the user can select between standard sharp or slowroll-off responses. in addition, the wm8741 includes a selection of advanced digital filter characteristics including non-half band filters and minimum phase filters. this flexibility provides arange of benefits, such as significantly reduced pre-ringing and minimal group delay. the internal digital filters can also be by-passed and the wm8741 used with an external digital filter. thewm8741 supports two connection schemes for audio dac control. the 2/3 wire serial control interface provides access to all features. a range of features can also be accessed by hardware controlinterface. the wm8741 is available in a convenient 28-ssop package, and is pin compatible with the wm8740.wm8741特色
