Analog Devices Inc. ADG411BRU Precision Analog Switch

The ADG411BRU from Analog Devices Inc. is a high-performance monolithic CMOS device comprising four independently selectable single-pole, single-throw (SPST) switches. This precision analog switch is designed to provide superior switching performance for precision applications in instrumentation, data acquisition, and process control systems.

With its low power dissipation and single-supply operation ranging from 10.8 V to 16.5 V, the ADG411BRU is an ideal choice for battery-powered and portable equipment. The device also offers a dual-supply operation mode, which extends its versatility, allowing it to function within a ±15 V range.

The ADG411BRU features an extremely low on-resistance (R_ON) of typically 35 ohms, which remains nearly constant over the full input signal range, ensuring excellent linearity and low distortion. This characteristic is particularly beneficial for precision analog signal handling, where maintaining signal integrity is crucial. Moreover, the R_ON match between channels and the R_ON flatness are well controlled, making this device suitable for applications requiring a high degree of precision and repeatability.

Another significant advantage of the ADG411BRU is its high switching speed, with t_ON of 175 ns and t_OFF of 145 ns, making it a good fit for high-frequency or rapidly changing signal environments. The device also features a low charge injection of 5 pC, which minimizes switching transients and thus reduces glitches and errors in precision measurement systems.

The ADG411BRU is provided in a TSSOP-16 package, which offers a compact footprint for space-constrained applications. Its enhanced electrostatic discharge (ESD) protection ensures robustness and reliability in harsh environments, safeguarding the device against unexpected electrical discharges.

In summary, the Analog Devices Inc. ADG411BRU analog switch combines low power consumption, high precision, and fast switching speeds, making it an excellent choice for engineers and designers looking to optimize their high-performance systems. Whether used in data acquisition systems, communication equipment, or medical devices, the ADG411BRU delivers consistent, reliable performance that you can count on.
