    Hi all,

    I have a problem with an analog switch DG201 in my analog design circuit. The circuit has 2 input at the early stage, v(t) and i(t). v(t) will be changed into TTL square wave and go through a sample and hold circuit. And the i(t) will be go through the sample and hold circuit as well. The waveform is shown in Figure where waveform A is the v(t) TTL square wave coming out from the opamp. Waveform B is the output of the sample and hold circuit for v(t).
    Now my problem is how am i going to obtain the waveform C and D by using the analog switch DG201? I am using labcenter proteus and there is no simulator model of DG201 in my simulation software. Is there any other switch/device can help me to obtain waveform C and D? Help me please. Thanks..

    Hello,

    Always get the datasheet if you do not know the IC.
    Here is the datasheet for the DG201-DG211.
