The ADG5421BRMZ from Analog Devices Inc. is a robust, high-performance dual single-pole single-throw (SPST) switch designed for precision applications that demand high reliability and protection against fault conditions. This component is part of a family of latch-up proof, monolithic CMOS devices that offer significant improvements over similar switches in terms of speed, leakage currents, and power dissipation.

Key Features

• Voltage Range: The device operates from a single 8 V to 44 V supply, or a dual ±4 V to ±22 V supply, making it versatile for various application needs.
• Enhanced Protection: It is designed with latch-up proof technology, ensuring that the device is protected against overvoltage conditions that can cause latch-up events in standard CMOS switches.
• Low On-Resistance: The ADG5421BRMZ features a low on-resistance (typically 10 Ω), which remains flat over the full analog signal range, ensuring excellent linearity and low distortion.
• High ESD Rating: Electrostatic discharge (ESD) protection is excellent, with a rating of 2 kV Human Body Model (HBM), providing robustness for handling and usage in harsh environments.

Applications

This switch is ideal for various applications where high-voltage operation and protection from fault conditions are necessary. It is commonly used in:

• Automated Test Equipment (ATE)
