MAX4721EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4721EUA+ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features low on-resistance of 4.5Ω maximum at +3V and 3Ω maximum at +5V. The device offers rail-to-rail signal handling, less than 0.5nA leakage current, and high off-isolation of -55dB at 10MHz. It includes break-before-make switching with a 1ns delay for the MAX4723 variant. The component is housed in an 8-pin µMAX package and supports an operating temperature range from -40°C to +85°C.
