Dual SPDT Analog Switches with Over-Rail Signal Handling
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 3.5Ωor 3.5Ω/7Ωon-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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
