Q: What is the function of an analog switch IC?

A: An analog switch IC is a device that can switch analog signals between different circuits or components. It acts as a gate that can either allow or block the flow of an analog signal.

Q: What is the difference between a SPDT switch and a DPDT switch?

A: A SPDT (single-pole, double-throw) switch has one input and two outputs . And that can be switched between. The switch has two inputs and two outputs that can be switched between.

Q: What is on-resistance in an analog switch IC?

A: On-resistance is the resistance of the switch when it is turned on. It determines how much voltage drop there is across the switch when it is conducting.

Q: What is charge injection in an analog switch IC?

A: Charge injection is a phenomenon where charges are injected into the circuit. When the switch is turned on or off. This can cause distortion or noise in the signal.

Q: What is capacitance in an analog switch IC?

A: Capacitance is the ability of the switch to store an electrical charge. High capacitance can cause attenuation or distortion of the signal.
