MAX4729EXT+ Description

Short technical summary and product information.

The MAX4729EXT+ is a low-voltage, single-pole/double-throw (SPDT) CMOS analog switch designed for applications requiring efficient signal routing. It operates from a single supply voltage of +1.8V to +5.5V, making it suitable for battery-operated equipment and low-power portable devices.

 

This switch features a low on-resistance of 3.5 Ohms at a +2.7V supply, with excellent flatness and match between channels. It offers a -3dB bandwidth of 300MHz and low on-capacitance of 19.5pF, ensuring good AC performance. The device consumes a minimal supply current of 1nA.

 

The MAX4729EXT+ is available in a compact 6-pin SC-70 package, suitable for surface mount applications. It is specified for operation over an extended temperature range of -40°C to +85°C, providing reliability in various environmental conditions.

 

Key applications include audio and video signal routing, low-voltage data-acquisition systems, sample-and-hold circuits, communications circuits, and as a direct replacement for relays.
