1 page ![]() 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 fea- ture low 3.5 Ω 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. For over-rail applications, these devices offer either the pass-through or high-impedance option. For the MAX4850/MAX4852, the signal (up to 5.5V) passes through the switch without distortion even when the posi- tive supply rail is exceeded. For the MAX4850H/ MAX4852H, the switch input becomes high impedance when the input signal exceeds the supply rail. The MAX4850/MAX4850H/MAX4852/MAX4852H are available in the space-saving (3mm x 3mm), 16-pin TQFN package and operate over the extended temper- ature range of -40°C to +85°C.
