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 0.6Ω on-resistance, making them ideal for 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.
