MAX4852ETE+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
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 3.5Ω 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.
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.
