ADG774ABRQZ-REEL7 (hereafter referred to as the ADG774) is a monolithic CMOS analog multiplexer (MUX) and analog switch fabricated on an advanced CMOS process. It is part of the family of high-performance, low-voltage analog switches, multiplexers, and demultiplexers that are available in industry-standard packages. The ADG774 offers the features needed to implement MEMs-based switching systems using a single chip.

Overview

The ADG774 is a general-purpose, high-density multiplexer and switch that provides a wide selection of designs. It is well suited for applications where precise switching and precise set-up are important. It provides a buffered output when the inputs are switched and can be used for either switching analog signals or for data acquisition in order to sample multiple inputs.

The ADG774 is an analog switch device that uses a CMOS structure, which allows for fast switching times and high channel isolation. It also offers low power consumption and low power dissipation for portable applications. It can be operated with a wide range of supply voltages from 2.6V to 5.5V, and has a power off mode to further reduce power consumption.

The ADG774 has three main advantages over other competing products: low power consumption, fast switching, and the ability to select multiple channels. Low power consumption is enabled by an innovative use of the internal amplifier circuitry. This allows for dynamic power management so that the device is always operating at the lowest possible voltage and current, thus consuming less power. Fast switching is accomplished through the use of an on-chip differential amplifier, which ensures that all signals are precisely switched on and off. The chip also has an internal pull-up resistor to reduce switching noise.

The ADG774 features a unique "multiplexer" function wherein the device can select up to four different channels from a single input. This allows for more complex signal routing applications, such as audio mixing or data acquisition. The multiplexing section consists of four 4-way multiplexers, each with a total of 16 individually selectable channels. Each multiplexer can be controlled separately, allowing for even more creative signal routing options.

Applications

The ADG774 is ideally suited for both high-speed and low-speed, low-power analog signal switching applications. It can be used in any application that requires high performance and low power consumption, such as medical instrumentation and industrial automation. It is also suitable for automotive and crossover applications, and can be used as an interface between high-performance, low-voltage devices. The ADG774 is also suitable for use in digital signal processing, audio and video switching, and gaming systems.

The ADG774 offers several advantages for signal routing and signal acquisition. With its 16 individually selectable channels, it is ideal for signal routing applications such as audio mixing and data acquisition. The ability to multiplex up to four channels from a single input also makes it useful for signal routing and signal acquisition. Additionally, the device features very low power consumption and a power-off mode, which make it ideal for portable applications.

Working Principle

The ADG774 is an analog multiplexer, switch and demultiplexer that uses a CMOS structure. It has a total of 16 independent channels and four 4-way multiplexers. Each channel can be turned on or off by applying a control voltage to its corresponding control input. Outputs of all enabled channels are then passed to the output buffer and onto the external circuit.

The ADG774 is designed for use in applications that require precise control over switching and/or data acquisition. An internal amplifier allows for precise control when switching and accurate set-up when sampling multiple inputs. The amplifier also implements dynamic power management so that the device can operate at the lowest possible voltage and current, thus consuming less power. The ADG774 also features a pull-up resistor that reduces switching noise.

Conclusion

The ADG774 is a versatile analog multiplexer, switch and demultiplexer that can be used in a variety of applications. It offers a high level of performance and flexibility, as well as low power consumption, which make it ideal for use in portable applications. Additionally, its unique multiplexing function allows for more complex signal routing and data acquisition applications. It is well-suited for use in audio and video switching, medical instrumentation, and industrial automation.
