MAX4901 - Low-RON & Dual-SPST/Single-SPDT Clickless Switches

Description

The MAX4901

MAX4905 switches feature negative signal capability that allows signals below ground to pass through without distortion.

The MAX4901/MAX4902 are a dual SPST (single-pole/single-throw) and the MAX4903/ MAX4904/MAX4905 are a single SPDT (singlepole/double-throw) configuration.

19-3775; Rev 2; 5/06 www.DataSheet4U.com Low-RON, Dual-SPST/Single-SPDT Clickless Switches with Negative Rail Capability General Description The MAX4901–MAX4905 switches feature negative signal capability that allows signals below ground to pass through without distortion. The MAX4901/MAX4902 are a dual SPST (single-pole/single-throw) and the MAX4903/ MAX4904/MAX4905 are a single SPDT (singlepole/double-throw) configuration. These analog switches operate from a single +1.8V to +5.5V supply and have low 0.6Ω on-resistance, making them ideal for switching audio signals. The MAX4905 includes a comparator that can be used for headphone detection or mute/send key function.
