Sample and Hold with CD4066

A sample and hold is like an analog memory. If The digital control A is low 4066 switch is open, and when A is high switch is closed. U2B is a buffer so as to ensure quick charging of C1 thru 4066 on resistance of 100E. U2A is a FET input opamp buffer which does not load or drain the cap C1.
