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. How do I choose the right analog switch?
When selecting an analog switch, you need to consider the number of channels, switching voltage range, on-resistance, off-leakage current, response time, and distortion metrics. The application environment and the nature of the signal (e.g. analog video, audio, or data) also need to be focused on.
-
3. 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.
-
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.
