I am using PIC18f in boost converter. The voltage across R2 is 5V with the input V. The value of V2 derease to 2.

You have to take care of internal ADC resistance. Connecting divider lic18f452 to pin probably would end up with changing signal characteristics. I would strongly recommend adding op amp buffer or changing the value of divider resistors. I had similar problem and solved it dataasheet Darko suggested, using a OpAmp voltage buffer. This lowered the ADC input impedance to almost nothing.

At the same time, I increased your resistor’s to ten times larger resistors, so they do not load the circuit you are measuring.

It is not necessary, but why not to do it, when OpAmp allows it. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

ADC of pic18f is not getting exact value of voltage datashete

Misal 79 4 Is the pin configured to be output? There can be a lot of reasons for that.

CP PIC18F Documentation

To short ADC sample time, check datasheet. The maximum recommended impedance for analog sources is 2. You need to put a small cheramic cap.

Darko Djuric 4 datashwet. I would like to see your schematic of the OpAmp buffer section, including the input resistors and output connection to PIC.

It should datxsheet down to almost zero volt, not only to 1. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.
