Working Principles
The ADG221KNZ is an analog switch that operates based on the principle of MOSFET transistors. When a control voltage is applied to the IN1 pin, the switch connects the COM pin to the NO pin, allowing the passage of analog signals. Conversely, when the control voltage is applied to the IN2 pin, the switch disconnects the COM and NO pins, blocking the signal flow.
Detailed Application Field Plans
The ADG221KNZ finds application in various fields where precise analog signal switching is required. Some potential application areas include: - Audio and video signal routing - Data acquisition systems - Test and measurement equipment - Industrial automation - Medical devices
