Basic Analogue and Digital parts

Hi there,
I was wondering if I can use the ADC0804 instead of the ADC0831 as specified in the parts list for the Basic Analogue and Digital book. My local electronics store does seem to have the 831.

The datasheet for the ADC083x chips can be found at the following link and should be able to give you enough information about the differences to help answer your question. I hope this helps. Take care.

For reconciling pin map and schematic differences, use the schematic in the Experiments with Renewable Energy PDF.
For code that works with the ADC0834, there's a PBASIC Program called ADCtest.bs2 in a zip file on the Experiments with Renewable Engergy page. You can add the A2D subroutine, variables and constants from the ADCtest code to examples in the Basic Analog and Digital text to make it work in place of the ADC0834 instead of the ADC0831.
