The ADG708BRUZ-REEL7 is a low-voltage, 8-channel unidirectional 8:1 multiplexer from Analog Devices (ADI), designed for high-performance signal routing in space-constrained applications. Packaged in a compact 16-pin TSSOP (3.0mm × 5.0mm × 1.05mm), this device operates from a single 1.8V to 5.5V or dual ±2.5V supply. It supports a bandwidth of 55MHz and features a low on-resistance (3Ω max) for minimal signal distortion, making it ideal for high-precision analog signal switching.

Key Features

This multiplexer offers ultra-fast switching times (25ns on-time, 15ns off-time) and a leakage current of 100pA, ensuring minimal crosstalk between channels. It operates across an extended temperature range (-40°C to +125°C) and maintains ±80dB channel isolation in off-state. With a quiescent power consumption of 5µW, it is optimized for low-power applications. The device supports TTL/CMOS-compatible control inputs and guarantees non-conductive switching (break-before-make) for glitch-free signal transitions.

Applications

Primarily used in data acquisition systems, communication interfaces, and audio/video signal routing, the ADG708BRUZ-REEL7 is critical for applications requiring precise multiplexing in industrial sensors, medical instrumentation, and automotive electronics. Its low voltage operation and compact form factor suit battery-powered devices, while its high bandwidth and isolation make it suitable for relay replacement in harsh environments. It is also employed in test equipment and portable instrumentation for efficient signal selection.

Summary

The ADG708BRUZ-REEL7 combines low power consumption, high-speed switching, and robust isolation in a compact package, positioning it as a versatile solution for analog signal multiplexing in industrial, automotive, and consumer markets. Its wide supply voltage range, minimal signal degradation, and extended temperature tolerance cater to applications demanding precision and reliability in space-constrained designs. This device remains a key component for optimizing signal integrity in mixed-signal systems.
