Working Principles

The ADG419BR is an analog multiplexer/demultiplexer that routes and switches signals between multiple input channels and output channels. It operates based on the control logic provided through the input control pins (IN1 to IN4) and channel select pins (S1 and S2). The enable input (EN) allows the device to be turned on or off.

When a specific channel is selected, the corresponding data input/output pin (D1 to D4) is connected to the common channel pin (e.g., D1 is connected to S1 when S1 is selected). The break-before-make switching action ensures that there is no overlap or short-circuiting during the transition between channels.

Detailed Application Field Plans

The ADG419BR finds applications in various fields where signal routing and switching are required. Some potential application areas include:

1. Test and Measurement Equipment: Used for signal conditioning, multiplexing, and demultiplexing in test setups.
2. Audio Systems: Enables audio signal routing and switching in mixers, amplifiers, and audio interfaces.
3. Communication Systems: Facilitates signal routing and switching in telecommunication equipment, routers, and switches.
4. Industrial Automation: Used for sensor signal conditioning, data acquisition, and control signal routing.
5. Medical Devices: Enables signal routing and switching in medical imaging equipment, patient monitoring systems, etc.

Alternative Models

• ADG418BR: Similar to ADG419BR but with 8 channels instead of 4.
• ADG417BR: Analog multiplexer/demultiplexer with 16 channels.
• ADG436BR: Precision analog switch with lower on-resistance and higher bandwidth.

(Note: The above alternative models are just a few examples. There are several other alternatives available in the market.)
