ADG412BRZ-REEL7 is a part of the Interface – Analog Switches, Multiplexers, Demultiplexers (ASMD) product family from Analog Devices. The device is a 40V absolute, 1nA leakage, quad, double-pole, double-throw (QDPDT) CMOS analog switch. It is designed to provide a high performance, low power analog switching solution.

The device is suitable for data- and audio-handling applications where good isolation, low power consumption and fast switching times are essential. It also has low charge injection capability and low off-state leakage current. It operates over a wide common-mode voltage range and is well-suited for applications involving battery-powered equipment.

The ADG412BRZ-REEL7 switch is made using a silicon-on-insulator (SOI) CMOS process with an internal package. The device features four single and one double SPST switch elements, each providing a break-before-make operation. Each switch element is controlled by an independent logic input with a propagation delay from the digital input to the analog output of less than 1 microsecond.

The device is designed to provide a very high RON which is typically about 10KΩ for most of the switches. The device also features integrated protection circuitry, which ensures that the analog switch does not suffer damage when an overvoltage condition is present. This integrated protection circuitry also helps prevent electrostatic damage.

The ADG412BRZ-REEL7 is designed to provide an very low-power analog switch. It typically consumes only 6μW of power, which makes it suitable for battery-powered applications. The device is rated for operating temperatures up to 125°C.

In terms of applications, the ADG412BRZ-REEL7 is well suited for low power hand-held, battery-operated and portable equipment. Such applications include audio routing and mixing, multiplexing and demultiplexing, and ADC/DAC switching. The device is also used for analog signal routing, routing of video signals, data retransmission and multiplexing, monitoring and operational amplifiers switching.

The working principle of the ADG412BRZ-REEL7 switch is fairly simple. It consists of four independent single-pole double-throw (SPDT) switches, each with a digital input and analog output. When the digital input is low, the corresponding switch is in an open state, allowing the analog output to float between the two analog input signals. When the digital input is high, the corresponding switch closes, connecting the analog output to the corresponding analog input.

The device also features low off-state leakage current and fast switching times. The off-state leakage current ranges from 0nA to 1nA, while the switching speed is typically less than 1 microsecond. The analog switch also has low charge injection capability and fast setup and hold times.

The ADG412BRZ-REEL7 switch is an advanced, low power, high performance analog switch. Its low power design and fast switching times make it suitable for many applications in both data- and audio-handling. Its high performance makes it suitable for multiplexing and demultiplexing, ADC/DAC switching, audio routing and mixing, and many more applications.
