MAX4658EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4658EUA+ is a single-pole/single-throw (SPST) CMOS analog switch designed for medium-voltage applications. It features a maximum on-resistance of 10Ω and supports continuous currents up to 150mA with peak currents reaching 300mA. The device operates within a supply range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations, accommodating rail-to-rail analog signals. Key electrical parameters include an off-leakage current of 1nA maximum at +25°C, a -3dB bandwidth of 210MHz, and charge injection of 1pC typical. It utilizes an 8-pin µMAX package and functions with TTL/CMOS compatible logic inputs.
