   产品概述 返回TOP

The CXAS42181 is a dual, high-speed, low-voltage, double-pole/double-throw (DPDT) CMOS analog switch that is designed to operate from a single 1.8V to 5.5V power supply. It features high-bandwidth (300MHz) and low on-resistance (4Ω TYP), targeted applications for audio switching.

The CXAS42181 consists of four SPDT switches. The configuration can be used as a bidirectional quad 2-channel multiplexer/demultiplexer with a single switch-enable (IN) input.

CXAS42181 can handle rail-to-rail analog signals and is available in Green TQFN-3×3-16L package.
