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.
The MAX4902/MAX4904/MAX4905 have internal shunt resistors to automatically discharge any capacitance at the NO_ and NC connection points.
This reduces click-andpop sounds that occur when switching audio signals between pre-charged points.
A break-before-make feature and auto-discharge also help to reduce popping.
These SPST and SPDT switches are available in space-saving 8-pin TDFN and 9-bump UCSP™ packages and operate over the -40°C to +85°C extended temperature range.
