ADG508AKRZ-REEL–Precision 8-Channel Analog Multiplexer IC
1. Overview
The ADG508AKRZ-REEL is a monolithic CMOS 8-channel analog multiplexer/demultiplexer from Analog Devices, designed for high-performance signal routing in precision electronic systems. It operates with a ±15V dual supply or +12V single supply, making it suitable for a wide range of industrial, medical, and communication applications. The device features low on-resistance (typically 100Ω) and fast switching speeds, ensuring minimal signal distortion while maintaining high accuracy. Its break-before-make switching action prevents channel overlap, enhancing system reliability.
2. Key Features
The ADG508AKRZ-REEL offers low power consumption (typically 5μW), making it ideal for battery-powered and energy-efficient designs. It provides excellent linearity (0.05% max) and low charge injection, critical for maintaining signal integrity in sensitive measurement circuits. The TTL/CMOS-compatible logic inputs ensure easy interfacing with microcontrollers and digital systems. Additionally, the chip is built with latch-up-proof construction, enhancing robustness in harsh environments. Its wide operating temperature range (-40°C to +85°C) ensures reliable performance across various industrial and automotive conditions.
3. Applications
This multiplexer is widely used in data acquisition systems, automated test equipment (ATE), medical instrumentation, and audio/video signal routing. It is particularly effective in sensor interfaces, process control systems, and communication switches, where precise analog signal management is essential. The ADG508AKRZ-REEL is also employed in battery monitoring systems, industrial automation, and aerospace electronics, thanks to its high reliability and low distortion characteristics.
4. Selection Advantages
Compared to competing analog switches, the ADG508AKRZ-REEL stands out due to its low on-resistance, high channel-to-channel isolation, and superior signal fidelity. Its break-before-make functionality prevents signal corruption during switching, a critical advantage in multiplexed measurement systems. The industry-standard SOIC-16 package ensures easy PCB integration, while Analog Devices' rigorous quality control guarantees long-term stability. Engineers favor this IC for its balanced trade-off between performance, power efficiency, and cost, making it a preferred choice for demanding analog switching applications.
