Successive Approximation ADC simulation in Proteus

[ppa88]

Here is a simulation of Successive Approximation type of ADC circuit using components(not a single ADC chip).
Helpful for anyone studying different types of ADC techniques.

Instructions for execution of the simulation are given on the schematic.

I realised that the the above circuit simulates better if the 1000K resistor between pin 3 and pin 6 of the opamp is removed. This puts the opamp comparator in open loop. I have yet to test this part on real hardware.
