ADG1611BCPZ-REEL7

The ADG1611BCPZ-REEL7 is a quadruple rail-to-rail CMOS analog switch made of voltage variable capacitors. It is designed primarily for switch and multiplexer applications in low-voltage communication and data acquisition systems. This part features very low RON and low switching power, making it suitable for precision switch and multiplexer applications, while still providing the necessary high performance switching operation.

Application Field

The ADG1611BCPZ-REEL7 can be used in a variety of applications, such as 3G and 4G cellular systems, data acquisition systems, and video and image processing systems. This part is suitable for switching of audio signals and data signals, as well as digital to analog and analog to digital conversion applications. The part is also suitable for precision switch applications in low-voltage power supplies such as mobile applications. Additionally, the part is suitable for use in shunt applications, such as linking of current loops in process control systems.

Working Principle

The ADG1611BCPZ-REEL7 utilizes a voltage-variable capacitance switching process to provide low-voltage and low-power operation. The part has four independent switches configured in a series configuration. Each switch contains two terminals, an input and an output. The input connects to a voltage rail while the output connects to an appropriate load or the common point between the switches. The voltage applied to the input will determine the capacitance of the switch, which in turn will determine the output current and voltage. The output current of the switch is governed by the voltage between the output and the common point, and can be adjusted by changing the capacitance of the switch.

The switches are controlled by two logic inputs that can be driven by either a digital logic voltage or a logic current. The logic levels of the inputs determine the on/off state of the switches. Additionally, the part provides a controlled turn-on and turn-off time, eliminating the need for external components. This makes the part ideal for low-noise switching applications.
