We estimate ADG1201 OFF leakage behavior with LTspice.
Our peak hold circuit have capacitance discharge and ADG1201 is good for discharge SW.
We need to estimate circuit behavior with LTspice.
But we have difference from datasheet spec to LTspice result.
Please advise us anything.
At first, we confirm ADG1201 characteristics with LTspice.
Below is datasheet condition.
We make below and attached LTspice circuit.
Result is below table
VDD=16.5V VSS=-16.5V VS and VD is in table.
-20nA leakage -I(V4)
|VD=10V||VS=10V||20nA leakage -I(V4)|
|VD=-10V||VS=10V||20nA leakage -I(V4)|
|VD=-10V||VS=-10V||-20nA leakage -I(V4)|
|VD=0V||VS=0V||less than fA -I(V4)|
20nA is over from datasheet spec.
Do we have any wrong ways?
Thank you very much.
