Hi all

I am a new member in this group since I have recently started dealing with electronics design I need some help from experienced people. We have designed a microcontroller training kit (AT89C51) where the voltage levels are 0 and 5 volts,
I have to assume you mean GND and Vcc in this case. Please correct me if I'm wrong here.
same goes for the ADC0804. My question is, if the input to the ADC0804 is a sine wave with +-2 amplitude what would be its voltage levels.
It's a mystery to me, just which voltage levels you mean.
I would be really glad if someone gave me the method to calculate it rather than just the answer.
It would be helpful if you would provide some additional information, including the reference voltage, sine wave frequency, sample rate, circuit diagram with indication of significant voltages, etc.

Thanks
Bye


At a minimum, I'd want to know what, exactly, is meant by "its voltage levels" since the device is an ANALOG-to-DIGITAL converter, and the designer should know those at the outset since they are externally applied.
