Working Principles

ADG441BR utilizes MOSFET-based technology to achieve precise signal routing. When a control voltage is applied to the EN (Enable) pin, the corresponding NO (Normally Open) pin connects to the common terminal, allowing the analog signal to pass through. The NC (Normally Closed) pins remain disconnected in this state. By controlling the EN pin, different NO pins can be selected, enabling flexible signal routing.

Detailed Application Field Plans

ADG441BR finds applications in various fields, including: 1. Audio systems: Signal routing in audio mixers, amplifiers, and equalizers. 2. Test and measurement equipment: Multiplexing of test signals in oscilloscopes, data acquisition systems, and function generators. 3. Communication systems: Switching between different antennas or channels in wireless communication devices. 4. Industrial automation: Signal routing in control systems, PLCs (Programmable Logic Controllers), and instrumentation.

Detailed and Complete Alternative Models

1. ADG442BR: Similar to ADG441BR but with 8 channels instead of 4.
2. ADG5404BRUZ: A quad SPST (Single-Pole Single-Throw) switch with lower on-resistance and higher bandwidth.
