Introduction

ADG781BCPZ-REEL is an analog switch IC produced by Analog Devices. It is part of their family of interface products, which includes analog switches, multiplexers, and demultiplexers. This product provides a low-voltage, high-performance analog signal switching solution. It also features a low power, small size, low leakage and low on-resistance making it ideal for a wide range of signal processing applications.

Application Field

ADG781BCPZ-REEL can be used in a variety of signal processing applications, such as switching between two or more analog signals, connecting analog signal sources to various loads, and providing voltage-level shifting between circuits of different levels. It can also be used for multiplexing and demultiplexing of analog signals to reduce the number of connections required for signal transmission. Additionally, this device can be used for level conversion between high and low voltage levels, and for signal conditioning, such as filtering and amplification.

Working Principle

The ADG781BCPZ-REEL is a dual CMOS analog switch with two independently controlled channels. Each channel can be configured as an independent single-pole single-throw (SPST) switch or an independent single-pole double-throw (SPDT) switch. It is digitally controlled through two control pins, which can be used to select the desired switch configuration.The switch is controlled by a logic signal (high or low) applied to the “Select” pin, where a logic high selects Channel A and a logic low selects Channel B. The output of this switch is then connected to the desired destination.The power supply ranges from 4.5V to 18V, allowing for flexibility in different applications. It also features a low-power shutdown mode, which is ideal for battery-operated applications.The ADG781BCPZ-REEL has a low-power consumption and a low-leakage current design, making it suitable for a wide range of signal processing applications. It is also designed to operate over a wide range of temperatures, with a maximum junction temperature of +125°C.

Conclusion

The ADG781BCPZ-REEL is an ideal solution for a wide range of analog switching, multiplexing and demultiplexing applications. It is suitable for low-voltage, power supply, and low-power applications, and can be used to switch between high voltage levels and low voltage levels. With its low power consumption, low leakage, and wide operating temperature range, the ADG781BCPZ-REEL is a suitable choice for analog signal processing.
