hello guys,
can anyone help me with an adc0804 tester circuit other than the basic one which is found in the datasheets?

i just want to test the adc0804 ic since it cannot be tested using universal ic testerWhat do you want to test?
Yes, I need to do a functional test so that I can use this ic without any problem.That doesn't answer out question.
You are just repeating your original question.
Do you just want to do just a basic functional test?
Sorry i meant checking the ic's total unadjusted error which should be within the range (+/- )1 LSBWhat "full-scale properties"?
Do you have the circuit diagram for this?One way to do that test is to use a DAC that has more bits resolution and an error must less than 1 LSB of the ADC value (say 1/10th or less) to provide a test voltage.
The output of the DAC goes to the input of the ADC.
Then you digitally increase the output of the DAC from 0V to full-scale using a microprocessor while monitoring the digital output of the ADC.
From that the microprocessor can calculate the deviation of each output bit's error from the ideal.
No. That would depend upon the ADC you want to test, the DAC you want to use, as well as which microprocessor will control the testing.Do you have the circuit diagram for this?
I want to test adc0804, but i dont know about which dac and microprocessor should be used. Also, I am not familiar with the programming too. Can i use microcontroller instead?No. That would depend upon the ADC you want to test, the DAC you want to use, as well as which microprocessor will control the testing.
Are you familiar with microprocessor programming?

Can i chat with u online?Because its a very urgent matter. My email id <snip>No. That would depend upon the ADC you want to test, the DAC you want to use, as well as which microprocessor will control the testing.

"How to program PIC microcontroller" is a long tutorial that can't be done here.How to program PIC microcontroller to use it as DAC ? Given set of digital inputs, I have to convert each of them to analog voltages with some specific equal time periods?
