DG333ALDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG333ALDQ-T1-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It integrates four independently controlled switches in a 20-pin TSSOP package, designed for high-accuracy analog signal routing. The device operates on dual supplies ranging from ±4 V to ±22 V or a single supply up to 36 V. Key electrical characteristics include a typical channel on-resistance of 25 Ω with a maximum of 90 Ω across the full temperature range, and low off-leakage current capped at 20 nA. The DG333AL variant features micro-power operation with supply currents under 1 μA, making it suitable for battery-powered applications.
