Analog switches handle continuous voltage/current signals with minimal distortion, while digital multiplexers route discrete logic levels (0/1). Analog versions prioritize parameters like on-resistance and bandwidth for signal integrity.
Key factors include on-resistance (causes voltage drops), charge injection (introduces glitches), and bandwidth (limits frequency response). High-performance switches minimize these to maintain gain precision and linearity.
Yes, specialized high-voltage analog switches (e.g., up to ±30V) are available for industrial control systems, but standard switches typically operate at ±15V or lower. Always check voltage ratings for compatibility.
