MAX4655EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4655EUA+ is a single-pole/single-throw (SPST) CMOS analog switch designed for high-current applications. It features a maximum on-resistance of 10Ω and supports continuous currents up to 300mA with peak capabilities of 400mA. The device operates within a supply range of ±4.5V to ±20V or +9V to +40V, enabling rail-to-rail signal handling. Key electrical parameters include an off-leakage current of 1nA max at +25°C, a typical turn-on time of 110ns, and a -3dB bandwidth of 210MHz. It utilizes an 8-pin µMAX package and functions across a temperature range of -40°C to +85°C.
