icl8038芯片多少钱，信号发生器芯片

1，信号发生器芯片

ICL8038，跟MAX038功能一样，不过价格很贵，20-30元/片，而且不可能产生20MHz那么高频率的正弦波。你要做那么高频率的，一般要用FPGA（或单片机）+DDS的方法。

The function generator weighs the wave form generator , is one kind of signal source in common use. The function generator major part giving birth to a child at present in the homeland are to make use of discrete component made up of , the armrest changes a measuring range coming moving , whose volume is big, reliability , accurate degree are all comparatively bad , can not satisfy scientific research , the call for giving birth to a child. With the fact that the large-scale integrated circuit and monolithic machine promptness develop, have been providing the possibility that the instrument renovates and upgrades right now. Our country makes use of the function generator that large-scale integrated circuit ICL8038 is composed of in recent years , a series being in progress debugs and tests on the spot, result is indicated being able to substitute the dummy load in the past completely. Make use of the ICL8038 chip and connect with a few components, the technology is advanced with regard to being able to manufacture mass , structure is deft , price is cheap , use is broad multifunctional function generator. Be in the above-mentioned basis going ahead , control if making use of the monolithic machine to be in progress, be to become the multifunctional intelligence function generator, now that it being able to produce various wave form, frequency and amplitude, and energy being able to demonstrate new creation wave form with the digital form are programmed. Make use of monolithic machine arithmetic and store a function, being able to work out a series to improve accurate degree , increase the functional software. This has significant effect to function generator accurate degree rise , the volume contraction and functional sharpening. The instrument is composed of several following parts: Function generator , real effective value change-over circuit, A/D and D/A change-over circuit, monolithic machine minimum system, demonstrate the keyboard and the control circuit. 题目翻译如下Multifunctional function generator design。文章有些长、、望认真看完、、标准人工翻译、、希望可以帮助你、、
