pass filtering to avoid degrading the perform-
ance of the ADC driver and ADC.
4. Observe the ADC output with demo circuit
DC718, a USB cable, a Windows computer, and
Linear Technology's QuickEval-II data process-
NOTE. Even a high-quality signal
synthesizer will still have noise
and harmonics that could be
attenuated with a low-pass or
band-pass filter. For good-quality
high order filters, see TTE, Lark
Engineering, or equivalent.
