DG409EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409EUE+ is a dual 4-channel CMOS analog multiplexer/demultiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with single supplies from +5V to +30V or dual supplies from ±5V to ±20V. The device features a maximum on-resistance of 100Ω, guaranteed channel matching of 8Ω max, and on-resistance flatness of 9Ω max. Charge injection is limited to 15pC max, while input leakage current remains below 5nA at +85°C. It provides ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.
