Sample Output of 8-bit A/D Converter at 5KHz

[EvLer]

Can anyone give me some idea of what is a possible output of analog-digit. converter 8-bit resolution. I don't have an opportunity to plug one in, but need some sample data... Let't say input frequency is 5KHz.

Thanks!

The output of an 8-bit ADC is one byte per conversion period, where the byte value shows where the input voltage is with respect to the reference voltage. The relationship to the reference voltage varies with the ADC, but a typical arrangement would be for the output byte to show where the input voltage is between the reference voltage and ground.

So if you have a 5kHz input voltage that swings between a 5V reference voltage and ground, then the 8-bit output values will vary between 0x00 and 0xFF to follow that input waveform.
