General Description

The MAX4850/MAX4850H/MAX4852/MAX4852H family of dual SPDT (single-pole/double-throw) switches oper ate from a single +2V to +5.5V supply and can handle signals greater than the supply rail. These switches feature low 3.5Ω or 3.5Ω/7Ω on-resistance with low on capacitance, making them ideal for switching audio and data signals. The MAX4850/MAX4850H are configured with two SPDT switches and feature two comparators for head phone detection or mute/send key functions. The MAX4852 has two SPDT switches with no comparators for low 1µA supply current.
