... 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. For over-rail applications, these devices offer either the pass-through or high-impedance option. For the MAX4850/MAX4852, the signal ( ...

... Detailed Description The MAX4850/MAX4850H/MAX4852/MAX4852H are low on-resistance, low-voltage, analog switches that operate from a +2V to +5.5V single supply and are fully specified for nominal 3.0V applications. These devices feature over-rail signal capability that allows signals up to 5.5V with supply voltages down to 2.0V. These devices are configured as dual SPDT switches. ...
