greetings everyone.
im building a digital oscilloscope (to use on a PC) for a project in
school
but im running into trouble with the ADC im using because it says to use
separate grounds and VCC for the digital and analogue parts, but
browsing around i4ve seen designs that have a COMMON VCC and grounds,
with some capacitors (for filtering noise i imagine)
if anyone who has worked with ADC4s (or digital oscilloscopes for that
matter!) at high freqs (5-20 MHz) has any ideas or experiences that can
help me please repply.
thanks
