MAX4901ETA+T

Price range: $1.47 - $4.19

The MAX4901–MAX4905 switches feature negativesignal capability that allows signals below ground to passthrough without distortion. The MAX4901/MAX4902 are adual SPST (single-pole/single-throw) and the MAX4903/MAX4904/MAX4905 are a single SPDT (single-pole/double-throw) configuration. These analog switchesoperate from a single +1.8V to +5.5V supply and havelow 0.6Ω on-resistance, making them ideal for switchingaudio signals.The MAX4905 includes a comparator that can be usedfor headphone detection or mute/send key function. TheMAX4902/MAX4904/MAX4905 have internal shunt resistorsto automatically discharge any capacitance at theNO_ and NC connection points. This reduces click-and-popsounds that occur when switching audio signalsbetween pre-charged points. A break-before-make featureand auto-discharge also help to reduce popping.These SPST and SPDT switches are available inspace-saving 8-pin TDFN and 9-bump UCSP™ packagesand operate over the -40°C to +85°C extendedtemperature range.ApplicationsCell PhonesMP3 PlayersNotebook ComputersPDAs and Handheld Devices
