The ADG444BR-REEL is a monolithic CMOS device comprising four independently selectable switches, designed by Analog Devices Inc., a leader in high-performance semiconductors. This product is part of the ADG444 series and comes in a tape and reel package, which is ideal for automated assembly processes. The device is well-suited for applications that require precise signal routing and is commonly used in communication systems, test equipment, and data acquisition systems.

Each switch of the ADG444BR-REEL conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. This feature makes the device an excellent choice for multiplexing and demultiplexing applications. Moreover, with its low power dissipation, it is a perfect fit for power-sensitive applications.

Key Features

• Low On Resistance: The switch's on resistance is typically below 45 ohms, ensuring minimal signal distortion and voltage drop across the switch.
• Single or Dual Supply Operation: The ADG444BR-REEL can operate from a single supply range of +12 V to +30 V, or from dual supplies of ±5 V to ±20 V, providing design flexibility.
• Low Power Consumption: The device features ultra-low power consumption, making it ideal for portable and battery-powered instruments.
• Fast Switching Times: With tON of 175 ns and tOFF of 145 ns, the device ensures rapid signal switching.
• Enhanced ESD Protection: It offers excellent electrostatic discharge (ESD) protection, enhancing its durability and reliability in harsh environments.

Applications

• Audio and video routing
• Data acquisition systems
• Communication systems
• Relay replacement
• Automatic test equipment

The ADG444BR-REEL's robust design and versatile features make it a highly reliable and efficient choice for designers looking to improve performance while maintaining or reducing power consumption. Its compact form factor and ease of integration into existing systems further enhance its appeal to engineers across various industries.
