Product details

Single SPST-NC analog switch in 8-SOIC

It routes one analog or digital signal channel with a 1:1 multiplexer/demultiplexer configuration, breaking the connection when the control input is deasserted. Key specs include a maximum on-resistance of 20 Ohm, switching times of 150ns on and 100ns off, and a low charge injection of 2pC. Typical applications include audio signal routing, data acquisition systems, and test equipment where a low-resistance, fast-switching normally-closed path is needed.

The 20 Ohm max on-resistance is the dominant contributor to insertion loss in the signal path.

Frequently asked questions

Is MAX4515ESA+ equivalent to MAX4517ESA?

The MAX4517ESA is a different device in the same family — it is a dual SPST-NO switch, while the MAX4515ESA+ is a single SPST-NC switch. They are not pin-compatible or functionally equivalent. For a single normally-closed switch in 8-SOIC, the MAX4515ESA+ is the correct part.
