MAX4729EXT+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4729EXT+T is a single-pole/double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from +1.8V to +5.5V and features a low on-resistance of 3.5Ω at a +2.7V supply. The device provides excellent AC characteristics, including a -3dB bandwidth of 300MHz and low on-capacitance of 19.5pF. It consumes typically only 1nA of supply current, making it suitable for low-power applications. The component is specified over an extended temperature range of -40°C to +85°C and is housed in a compact 6-pin SC70 package.
