Working Principles

The DG201ACSE operates by controlling the connection between its input and output terminals using a control voltage. When the control voltage is high, the switch is closed, allowing the signal to pass through. Conversely, when the control voltage is low, the switch is open, isolating the input and output terminals.

Application Field Plans

The DG201ACSE finds applications in various fields, including:

1. Audio Systems: Enables signal routing in audio mixers, amplifiers, and equalizers.
2. Communication Systems: Facilitates signal switching in telecommunication devices and network equipment.
3. Test and Measurement Instruments: Provides flexible signal routing capabilities in oscilloscopes, function generators, and data acquisition systems.
4. Industrial Control Systems: Allows for precise control of analog signals in industrial automation and process control systems.
