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 is a special purpose analog switch?
Special purpose analog switches are switches designed for specific applications with unique features or specific electrical characteristics, such as support for high voltage, high frequency, low leakage current, and low distortion. These switches are suitable for specific industrial, medical or high performance signal processing tasks.
-
3. 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.
-
4. How is the distortion and signal integrity of analog switches ensured?
High-quality analog switches are designed with low on-resistance, low leakage current and low parasitic capacitance in mind to ensure that distortion is minimized and signal integrity is maintained during signal switching. This is critical for high-fidelity audio, precision instruments and data communications.
