General Description

The MAX4851/MAX4851H/MAX4853/MAX4853H family of quad single-pole/single-throw (SPST) switches operates from a single +2V to +5.5V supply and can handle signals greater than the supply rail. These switches feature low 3.5? on-resistance with 40pF on-capacitance or 7? on-resistance with 30pF on-capacitance, making them ideal for switching audio and data signals. The MAX4851/MAX4851H are configured with four SPST switches and feature a comparator for head phone detection or mute/send key functions. The MAX4853/MAX4853H have four SPST switches but do not include a comparator.
