The ADG417BRZ is a monolithic CMOS analog switch that operates from single power supplies up to 10 V and has low power consumption. It is designed specifically for low level signals and has numerous applications in a variety of analog signal conditioning and routing circuits. This device can isolated both high and low frequency signals for multiplexing, sample and hold operation, and signal mode isolation. In this article, we will discuss the application field, working principles and features of the ADG417BRZ analogue switch.

Application Field

The ADG417BRZ is a low power, low voltage analogue switch capable of handling very low level signals. Its applications are wide and varied, and include signal multiplexing, signal isolation, impedance matching, analogue-to-digital and digital-to-analogue conversion, and sample and hold operation. It is also used in applications such as power management, medical, audio and video signal processing and telecommunications.

Working Principle

At the heart of the ADG417BRZ is a fully functional CMOS analog switch. When the switch is in the “on” state, the capacitance between src and dst is minimized, allowing the signal to flow without losses. When the switch is in the “off” state, the capacitance between src and dst is maximized, preventing any signal from passing through. The ADG417BRZ potential divider is used to create a bias voltage that can be used to control the switching state of the device.

Features

The ADG417BRZ offers several features that make it desirable for many low level analog applications. It offers low on-resistance of 1Ω, fast switching times of 30ns, wide linearity range (-3dB to +3dB), and good isolation (200dB @ 1MHz). It is also available in a wide range of package options, including DIP, SOIC, QSOP, and TSSOP. The ADG417BRZ also comes with dual enable functions for ease of use.

In addition to its features, the ADG417BRZ is also very cost effective. Its low power consumption and high channel count make it a popular choice for multiplexing, sample and hold, and signal mode isolation applications. And, its small form factor allows it to be used in a variety of applications where space is a concern.

Conclusion

The ADG417BRZ is a versatile and cost effective monolithic CMOS analog switch that can be used in a variety of applications, from power management to signal conditioning and routing. It offers low power consumption, low resistances, fast switching times, wide linearity range, and good isolation. Its low cost and wide package options make it a good choice for multiplexing, sample and hold, and signal mode isolation applications.
