1. What is an analog switch and how does it work?
An analog switch is an electronic component that is capable of selecting, switching, or disconnecting in an analog signal path. It switches channels by means of a control signal (usually digital) so that analog signals can be transferred from one path to another.
-
2. What are the advantages of analog switches over relays?
Compared to mechanical relays, analog switches have no mechanical moving parts and offer faster switching speeds, longer lifetimes, lower power consumption, and smaller sizes. At the same time, analog switches have lower distortion, making them suitable for high-precision signal switching.
-
3. How are the power requirements for analog switches handled?
Analog switches typically require a bipolar power supply (e.g. ±5V) to handle positive and negative analog signals. Single-supply operation may also be required for some applications, and the design needs to ensure that the power supply matches the operating voltage range of the switch.
-
4. What are the electrical characteristics of special-purpose analog switches that I should be concerned about?
Electrical characteristics of special-purpose analog switches include high-voltage handling capability, wide bandwidth, low capacitance, and low leakage current. Different applications have different requirements for these characteristics, for example, high speed data communications require a wide bandwidth, while medical applications may require low leakage current and low distortion.
