Product details

The Maxim Integrated MAX4733EUA+ is a dual single-pole single-throw (SPST) analog switch with one normally-open and one normally-closed pole per circuit. It routes analog or digital signals up to 300 MHz bandwidth with a maximum on-resistance of 25 ohms, making it suitable for audio-path routing, signal multiplexing, and data-acquisition front-ends.

The -108 dB crosstalk at 1 MHz isolates channels. The 7.5 pC charge injection affects sample-and-hold circuits. The 300 MHz bandwidth supports video or fast digital muxing.

Package and rework consideration

The 8-uMAX/uSOP package has a 3.00 mm body width. It is surface-mount only.

Frequently asked questions

Can MAX4733EUA+ be used for audio signal switching?

Yes, the -108 dB crosstalk at 1 MHz and 300 MHz bandwidth keep audio-path bleed well below audible thresholds, and the 25 ohm on-resistance adds minimal attenuation in a line-level signal chain.

What is the on-resistance and how well do the channels match?

Maximum on-resistance is 25 ohms, and channel-to-channel matching is 200 milliohms typical. That means the two switch paths introduce nearly identical attenuation, which matters for balanced signal routing or differential measurements.
