I need to implement a very low voltage drop switch controlled by a microcontroller. I need it to connect (short) two nodes in my circuit for calibration purposes. One node is the input of an opamp (very high input impedance) and the other is the output of another opamp.
I thought about using a simple bjt, but it seems that its Vce drop is too high for my project. So I thought about other solutions like MOSFETs, but I don't know which one is more suitable for this goal.
The lower the voltage drop, the better. Any suggestions?
