MAX4655ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4655ESA+ is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations. The device features a maximum on-resistance of 10Ω at ±15V supplies and supports up to 300mA continuous current and 400mA peak current. It utilizes an 8-pin SOIC package with an exposed paddle, operating across a temperature range of -40°C to +85°C.
