1. 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.
-
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 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.
