Analog switch is a two or four pole switch that is used to support analog signals, such as audio or video signals. It is typically used to switch between two or more inputs without affecting the integrity of the signals. It is also used to connect two or more signals in parallel. The ADG407BNZ is particularly suitable for applications that require high power handling, low power consumption and stable operation.

The ADG407BNZ is a four-channel multiplexer/demultiplexer analog switch. It features a low-ohm ON resistance of 0.45 W and a high-ohm OFF resistance of over 1M W. These features make it suitable for applications that need accuracy, high speed, and low noise. The ADG407BNZ is designed to support both single-ended and differential signals. It features an input range of ±5 V, and can be powered by a single supply voltage of 3 V or 5 V.

The ADG407BNZ has two main modes of operation, direct and quad. In direct mode, the high-ohm OFF resistance and low-ohm ON resistance switched through the A, B, and C select pins can be used for signal routing. In quad mode, the A and B select pins are used to select either one of the four demultiplexed channels, which provide for fast switching of multiple inputs.

The ADG407BNZ is ideal for audio and video switching applications, such as video streaming and audio mixing. It is also suitable for data acquisition and control applications, such as industrial control systems and process automation. In addition, this switch can be used in computer and communication systems, such as routers and switches, and in medical and automotive applications.

The working principle of the ADG407BNZ is based on the application of charge transfer to achieve switching. The switch features four FET switches, each consisting of an N-channel MOSFET and a P-channel MOSFET, which are connected in anti-series. When the switch is ON, a charge transfer process is initiated, and the N-channel MOSFET is discharged and the P-channel is charged. This transfer causes a voltage difference across the switch, which is the ON state. When the switch is OFF, the transfer is reversed, which discharges the P-channel and charges the N-channel, resulting in the OFF state.

The ADG407BNZ is a high-performance, low-power device that offers a low-ohm ON resistance and a high-ohm OFF resistance. It is ideal for applications that require fast switching of multiple inputs and high power handling. The switch is capable of supporting single-ended and differential signals, making it suitable for a variety of audio and video applications. Its low power consumption and stable operation make it an ideal choice for industrial control and process automation applications.
