Analog Devices Inc. ADG408BRU: High-Performance CMOS Analog Multiplexer

The ADG408BRU is a precision monolithic analog multiplexer from Analog Devices Inc., a leader in high-performance analog technology. This device offers eight single-ended channels and is part of a series of high-performance, CMOS analog multiplexers and switches. The ADG408BRU is designed to provide superior performance and reliability for a wide range of data acquisition and control applications.

Featuring a low on-resistance (R<sub>ON) of typically 35 ohms and a very low R<sub>ON match between channels, the ADG408BRU ensures minimal signal distortion and attenuation. This makes it an excellent choice for precision applications where a low and consistent resistance path is critical. Additionally, the device boasts a wide signal range, which is fully specified to operate from a single +5 V supply or dual ±15 V supplies, providing flexibility in various system designs.

The ADG408BRU operates with a dual-mode interface, accepting both digital and analog input signals. This feature allows for easy integration into digital systems while preserving the integrity of analog signals. The TTL and CMOS compatibility of the control logic ensures that the device can interface with a broad range of microprocessors and digital systems without additional level-shifting circuitry.

With a breakdown voltage of 44 V and an ESD rating of 2000 V, the ADG408BRU is robust and suitable for demanding environments. The device is available in a TSSOP package, which is conducive to space-saving designs and is ideal for applications where board space is at a premium. The TSSOP package also provides enhanced thermal performance compared to traditional packages.

Applications for the ADG408BRU include data acquisition systems, test equipment, audio and video switching, and other situations where high-performance analog switching is required. With its combination of low on-resistance, high voltage capability, and flexible power supply options, the ADG408BRU is a versatile solution that can meet the stringent requirements of modern electronic systems.
