thanks dear for your reply, i have designed the circuit, from which i am geting the count different of about 5 to 10. i require 5 lakh count from ADC. i have used amplifier with 20 gain. now my input to the amplifier is about 2 to 5 mVolt. if i increase the gain noise problem comes and my count starts running. so can u help me to find a way to get 5 lakh count. waiting for ur reply....
Again!
Have you checked the Microchip website for design guidance? And the sites of other ADC manufacturers? And the sites of low-noise, high-precision linear IC specialists?
Do you have a decent textbook on analogue electronics?
Note that none of this has anything to do with Keil software tools - its all about analogue electronics!
do you have separate analog and digital grounds? do you ...?
read the references you have been give and FOLLOW THEM
