MAX4901EBL+T
Low-RON, Dual-SPST/Single-SPDT Clickless Switches with Negative Rail Capability
General Description
The MAX4901–MAX4905 switches feature negative
signal capability that allows signals below ground to pass
through without distortion. The MAX4901/MAX4902 are a
dual SPST (single-pole/single-throw) and the MAX4903/
MAX4904/MAX4905 are a single SPDT (single-
pole/double-throw) configuration. These analog switches
operate from a single +1.8V to +5.5V supply and have
low 0.6Ωon-resistance, making them idealfor switching
audio signals.
The MAX4905 includes a comparator that can be used
for headphone detection or mute/send key function. The
MAX4902/MAX4904/MAX4905 have internal shunt resis-
tors to automatically discharge any capacitance at the
NO_ and NC connection points. This reduces click-and-
pop sounds that occur when switching audio signals
between pre-charged points. A break-before-make fea-
ture and auto-discharge also help to reduce popping.
These SPST and SPDT switches are available in
space-saving 8-pin TDFN and 9-bump UCSP™ pack-
ages and operate over the -40°C to +85°C extended
temperature range.

ABSOLUTE MAXIMUM RATINGS
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.

specified analog signal ranges.
Note 7:The MAX4902/MAX4904/MAX4905 have an internal shunt resistor when, in off-state, will determine off-current.
