DG409AK – SILICONIX

Overview

The Siliconix DG409AK is a high-performance, dual 4-channel analog multiplexer designed for robust signal routing in demanding electronic systems. Its critical operational characteristic lies in its low on-resistance (100Ω typical) and excellent channel-to-channel matching (1.5Ω max), ensuring minimal signal attenuation and distortion. A key design consideration for applications utilizing this device is the trade-off between switching speed and power dissipation; while its 150ns switching times are suitable for many applications, designers must balance this with the potential for increased heat generation in high-frequency switching scenarios, particularly given its through-hole CERDIP package.
