ADG431BRZ - Precision Analog Switch from Analog Devices Inc.

The ADG431BRZ is a high-performance monolithic analog switch from Analog Devices Inc., designed to deliver exceptional signal accuracy and switching efficiency. This precision device is part of a series of iCMOS™ (industrial CMOS) switches that offer a range of benefits for a wide array of applications, including data acquisition systems, communication systems, and medical equipment.

Constructed with Analog Devices' innovative iCMOS technology, the ADG431BRZ provides a dual single-pole, double-throw (SPDT) switch configuration. This technology combines high-voltage silicon with submicron CMOS to offer improved performance characteristics compared to traditional CMOS switches. The result is a device with high bandwidth, low charge injection, and reduced power consumption.

The ADG431BRZ operates from a single +5 V to +16 V supply or a dual ±5 V to ±8 V supply, making it highly versatile for various circuit designs. It features a low on-resistance (typically 45 Ω) that remains flat over the full analog signal range, ensuring minimal distortion and consistent performance. The on-resistance match between channels and the flatness over the signal range contribute to the excellent signal integrity that the ADG431BRZ provides.

Switching times for the ADG431BRZ are fast, with t_ON typically at 45 ns and t_OFF at 25 ns, allowing for rapid signal routing and minimizing delay in critical signal paths. The device also boasts low power dissipation, which is crucial for power-sensitive applications. Additionally, it has a low charge injection of 1 pC, which minimizes switching transients and is beneficial for precision applications where signal fidelity is paramount.

The ADG431BRZ comes in a robust 16-lead SOIC (Small Outline Integrated Circuit) package, ensuring reliability and ease of integration into various circuit designs. It also features TTL/CMOS-compatible digital inputs, making it easy to interface with a wide range of logic controllers and microprocessors.

In summary, the ADG431BRZ from Analog Devices Inc. is a high-quality, precision analog switch that offers reliability, efficiency, and accuracy for demanding applications that require the best in signal switching performance.
