The ADG802BRMZ is a type of analog switch, multiplexer, and demultiplexer, used for a variety of applications. It is designed specifically for low-power applications that require good on-resistance and off-state leakage current characteristics, as well as low-voltage operation.

Application Field

The ADG802BRMZ is ideal for a wide variety of applications, ranging from audio/video switching to automotive and consumer electronics. The device has excellent on-resistance and low off-state leakage current, making it well-suited for low 'on' resistance and very low current application switching.

In addition, the ADG802BRMZ is also useful in multiplexers and demultiplexers. It can be used to switch between up to four analog signals. This is done by using a single 'common' input and a group of four 'selection signals' which are used to determine which of the four inputs is selected. The ADG802BRMZ can also be used as a demultiplexer, where it is used to select one of two input signals and send it to the output.

The device also has low power consumption, making it suitable for battery-powered applications. The device has low polarization loss and a fast switching time, making it suitable for high-speed applications such as audio and video switching. The device is also tolerant to a wide range of input voltages, making it suitable for both low- and high-voltage applications.

Working Principle

The ADG802BRMZ is based on an analog CMOS technology. The device is constructed from n- and p-channel field effect transistors (FETs). The FETs have an insulated gate structure and serve as both the switches and the input and output devices.

The device is basically a four-channel switch and can be used as a multiplexer or demultiplexer. The switching is controlled by a single digital input. This input can be either a voltage or a logic signal. When the single digital input is set to 0, the channels will be switched off. When set to 1, the channels will be switched on.

The ADG802BRMZ uses a high-impedance FET switch configuration. This means that when the switch is in the 'off' condition, the switch will not consume any current. This makes the device suitable for low power applications. The device also has a fast switching time, making it suitable for high-speed applications.

The ADG802BRMZ also has an adjustable output impedance. This means that the output impedance can be adjusted to ensure the switch has a low on-resistance and low leakage current. The device is also temperature stable and able to handle wide input voltage ranges.

Conclusion

The ADG802BRMZ is an analog switch, multiplexer, and demultiplexer, designed for low-power applications which require good on-resistance and low off-state leakage current characteristics. It can also be used to switch between up to four analog signals, making it suitable for audio/video switching, automotive, and consumer electronics. The device is based on an analog CMOS technology, has low power consumption, low polarization loss, fast switching time, and is tolerant to a wide range of input voltages.
