The ADG749BKSRELL7 is a low charge injection, quad SPST (single-pole, single-throw) switch from Analog Devices (ADI). It's designed for applications requiring high accuracy and minimal signal distortion, particularly in data acquisition and signal processing systems. The quad configuration allows for switching of four independent signal paths.

Applications

• Data acquisition systems
• ATE (Automated Test Equipment)
• Sample-and-hold circuits
• Precision instrumentation
• Audio and video switching

Features

• Low charge injection: Minimizes signal distortion during switching.
• Low on resistance (RON): Reduces signal loss and improves accuracy.
• Fast switching speeds: Enables high-speed data acquisition and signal processing.
• Single-supply operation: Simplifies power supply design.
• TTL/CMOS compatible logic: Easy interfacing with digital control signals.
• Small footprint: Allows for efficient PCB layout.

Benefits

• Maintains signal integrity by minimizing charge injection and signal loss.
• Improves the accuracy and precision of measurement systems.
• Enables high-speed data acquisition and signal processing.
• Simplifies system design and reduces component count.
• Provides compatibility with a wide range of digital logic families.
• Reduces PCB size and cost.

Additional Details

The ADG749BKSRELL7 operates from a single supply voltage of 2.7 V to 5.5 V. It features a typical on-resistance of 2.5 ohms and a charge injection of less than 1 pC. The device is available in a small MSOP package and operates over an industrial temperature range of -40°C to +85°C. The 'KSRE' portion of the part number specifies the package type and tape & reel orientation. This switch is ideal for applications where high accuracy and minimal signal distortion are critical.
