The MAX4850/MAX4850H/MAX4852/MAX4852H family of dual SPDT (single-pole/double-throw) switches operate 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 headphone 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 positive 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 temperature range of -40°C to +85°C.
