i am using AT 89S52 microcontroller and we want to measure average value of a signal with frequency between 10khz-15khz. is there any ADC IC available which will directly give me an average value ? if there is any other solution please let me know.
Do you mean RMS?
Analog Devices AD736
Thank you for your help.As you suggest IC AD736 ,we are working on it.If any trouble will come across i will tell you.
Thank you once again.
i want to add one more query to my previous one.that is "am using AT 89S52 microcontroller and i want to measure average value of a signal with frequency between 10khz-15khz with voltage range upto 5V. is there any IC available which will directly give me an average value ? if there is any other solution please let me know."
Thank you
You still haven't answered the question: Do you mean RMS?
If not, what do you mean by "average"?
Yes i mean to say RMS.
The datasheet of the AD736 gives the input/output range. It should be no problem to add an opamp and/or voltage divider (with trimm potentiometer) to fit your requirements. Besides - this is not KEIL stuff.
