ADG839YKSZ-REEL7 devices fall under the category of Interface - Analog Switches, Multiplexers, Demultiplexers. These components provide an interface between digital and analog systems, allowing digital signals to drive a unique set of analog inputs or outputs. In this article, we take a look at the application field and working principle of ADG839YKSZ-REEL7.

ADG839YKSZ-REEL7 devices are typically used in multi-channel signal conditioning, multiplexing, and switching applications. The device is a very low on-resistance switch, allowing signals to pass quickly with minimal distortion. It also has an integrated charge pumps which allows the device to operate at very high speeds, up to 200 MHz.

The application field of ADG839YKSZ-REEL7 is varied, and includes audio and video signal routing, data conversion, amplifier control, and digital-to-analog converter (DAC) switching. This device is also well-suited for use in RF signal routing, providing fast switching with minimal losses due to its low on-resistance. Additionally, it can be used in applications where power efficiency is a priority as the device only consumes low quiescent current.

The basic working principle of the ADG839YKSZ-REEL7 lies in the relay switch architecture. The device has three independent switches with a total maximum on-state resistance of 5 ohms. The switches each have an enable pin, and these pins can be connected either directly to the power source, or through a logic input. When the enable pin is connected to the logic input, the switch is controlled by the logic input and transmits the signal across the on-state resistance of the open switch. When the enable pin is connected to the power source, the switch is in the open position and no current flows through the device.

Additionally, the ADG839YKSZ-REEL7 also has a charge pump circuit which provides power to the switches, allowing them to operate at higher speeds. The charge pump circuit is able to switch the voltage across the on-state resistance from 0-5 volts in order to reduce power loss and allow for faster switching times.

In summary, the ADG839YKSZ-REEL7 is an extremely versatile switch that is able to be used in a wide range of applications including audio and video signal routing, data conversion, amplifier control, and DAC switching. The switch’s relay-style architecture and integrated charge pump provide high-speed, low distortion, and low power switching.
