DG441LDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441LDQ-T1-E3 is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a typical on-resistance of 17 Ω and fast switching times with a maximum turn-on time of 60 ns and turn-off time of 35 ns at room temperature under standard test conditions. It offers low leakage current, high off-isolation, and minimal crosstalk. The component is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) and supports an operating temperature range from -40 °C to +85 °C.
