Maxim
Datasheet
The MAX14759/MAX14761/MAX14763 analog switches
are capable of passing bipolar signals that are beyond
their supply rails. These devices operate from a single
+3.0V to +5.5V supply and support signals in the -25V
to +25V range.
The MAX14759 is a single-pole/single-throw (SPST) ana-
log switch, while the MAX14761 is a dual-SPST analog
switch. The MAX14763 is a single-pole/double-throw
(SPDT) analog switch.
The MAX14759 features 1I (max) on-resistance with
a Q200nA (max) on-leakage current. The MAX14761/
MAX14763 feature 2I (max) on-resistance with a Q100nA
(max) on-leakage current. The low on-resistance and
high bandwidth allow use in digital- and analog-signal
switching applications.
The MAX14759/MAX14763 are available in an 8-pin
(3mm x 3mm) TDFN package. The MAX14761 is avail-
able in a 10-pin (3mm x 3mm) TDFN package. These
devices are specified over the -40NC to +85NC extended
temperature range.
