Quad SPST Switches with Over-Rail
Signal Handling
General Description
The MAX4851/MAX4851H/MAX4853/MAX4853H family
of quad single-pole/single-throw (SPST) switches oper-
ates from a single +2V to +5.5V supply and can handle
signals greater than the supply rail. These switches fea-
ture low 3.5Ω on-resistance with 40pF on-capacitance
or 7Ω on-resistance with 30pF on-capacitance, making
them ideal for switching audio and data signals.
The MAX4851/MAX4851H are configured with four
SPST switches and feature a comparator for head-
phone detection or mute/send key functions. The
MAX4853/MAX4853H have four SPST switches but do
not include a comparator.
For over-rail applications, these devices offer either the
pass-through or high-impedance option. For the
MAX4851/ MAX4853, signals greater than the positive
supply (up to 5.5V) pass through the switch without dis-
tortion. For the MAX4851H/MAX4853H, the switch input
becomes high impedance when the input signal
exceeds the supply rail.
The MAX4851/MAX4851H/MAX4853/MAX4853H are
available in the space-saving, 16-pin, 3mm x 3mm thin
QFN package and operate over the -40°C to +85°C
extended temperature range.
