1. 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.
-
2. How are analog switches used in audio and video applications?
In audio and video applications, analog switches are used to switch signals between different sources or devices. It is necessary to ensure that the switch has sufficiently low distortion and signal attenuation, and provides smooth switching to avoid introducing noise or interference.
-
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.
