Technical Specification :

Analog to Digital Converter composes of the devices transforming an analog signal into discrete signals.
It converts continuously varying signal with time into the discrete signal. The Analog to
Digital converter Scientech 2601 demonstrates two techniques:
4-bit staircase ramp ADC
8-bit successive approximation ADC
A/D Converter Trainer is an ideal teaching aid to enhance education, training,
skills & development amongst our young minds.
