ADG508AKRZ CMOS analog multiplexer
The ADG508AKRZ is an 8-channel CMOS analog multiplexer designed by Analog Devices (ADI) for high-precision signal routing in industrial and instrumentation applications. Built on an enhanced LC²MOS process, it supports a wide single/dual-supply voltage range of 10.8V to 16.5V, enabling flexible power integration.
The analog chip features a 300Ω (max) on-resistance with ±15Ω channel-to-channel matching, ensuring minimal signal distortion and stable operation across all channels. Its break-before-make switching mechanism prevents short circuits during transitions, while ultra-low leakage current (20pA typical) makes it ideal for high-impedance circuits. The ADG508AKRZ operates over an extended temperature range (-40°C to +85°C) and comes in a compact 16-pin SOIC package, supporting surface-mount assembly for space-constrained designs.
