MAX4904：Low-RON, Dual-SPST/Single-SPDT Clickless Switches with Negative Rail Capability
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 (single-pole/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-and-pop 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.
