DG419LDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG419LDY is a precision CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated, featuring a single-pole/double-throw (SPDT) configuration. It provides a maximum on-resistance of 35Ω with guaranteed matching of 3Ω and flatness of 4Ω. The device operates on dual supplies ranging from ±4.5V to ±20V or a single supply from +9V to +36V. It supports +3V logic compatibility with input thresholds of 0.8V for low and 2.0V for high. Key electrical parameters include a turn-on time of 175ns, turn-off time of 185ns, off-leakage current under 5nA at +85°C, and charge injection of 15pC. The component is housed in an 8-pin SOIC package and functions within an extended temperature range of -40°C to +85°C.
