The ADG444BR from Analog Devices Inc. is a monolithic CMOS device comprising four independently selectable single-pole, single-throw (SPST) switches. This component is an ideal choice for precision analog signal switching due to its low power consumption and high switching speeds. The ADG444BR is well-suited for applications in test equipment, data acquisition systems, and communication devices where reliable and efficient signal routing is required.

Key Features

• Low Power Consumption: The ADG444BR operates with a very low power requirement, conserving energy and ensuring minimal impact on power-sensitive systems.
• Wide Supply Range: With a dual supply range of ±4.5 V to ±18 V or a single supply range of 9 V to 36 V, the ADG444BR provides flexible options for various application voltage requirements.
• Low On Resistance: The switch features a low on resistance (typically 45 Ω), which is beneficial for maintaining signal integrity and reducing voltage drops across the switch.
• High Switching Speeds: Fast transition times (tON and tOFF) of typically 175 ns and 145 ns, respectively, allow for quick signal routing, making the ADG444BR suitable for high-frequency applications.
• Improved Off Isolation: The device offers enhanced off isolation, minimizing the potential for signal leakage between channels when switches are in the off state.
• Extended Temperature Range: The ADG444BR is designed to operate over an industrial temperature range of -40°C to +85°C, ensuring reliable performance under varying environmental conditions.

Applications

• Audio and Video Switching
• Automatic Test Equipment (ATE)
• Data Acquisition Systems
• Communication Systems
• Sample Hold Systems
• Battery Powered Systems

The ADG444BR is available in a 16-lead standard plastic DIP package and a 16-lead surface-mount SOIC package. Its robust design and versatile features make it a reliable and efficient solution for designers looking to enhance their analog signal switching capabilities.
