MAX339MJE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339MJE is a dual-channel analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two independent SP4T (Single Pole, Four Throw) switching circuits within a single package. The device supports a wide single-supply voltage range of 4.5V to 30V and a dual-supply range of ±4.5V to ±20V. It utilizes CMOS technology for low power consumption and high speed. Key electrical characteristics include a maximum on-resistance of 400 ohms and a channel-to-channel matching of 4 ohms. The component operates reliably across an extended industrial temperature range from -40°C to +85°C.
