Monolithic CMOS Analog Switches
The DG401, DG403 and DG405 monolithic CMOS analog
switches have TTL and CMOS compatible digital inputs.
These switches feature low analog ON resistance (<45Ω)
and fast switch time (t
ON
< 150ns). Low charge injection
simplifies sample and hold applications.
The improvements in the DG401/403/405 series are made
possible by using a high voltage silicon-gate process. An
epitaxial layer prevents the latch-up associated with older
CMOS technologies. The 44V maximum voltage range
permits controlling 30V
P-P
signals. Power supplies may be
single-ended from +5V to +34V, or split from
±5V
to
±17V.
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with analog
signals is quite low over a
±15V
analog input range. The three
different devices provide the equivalent of two SPST (DG401),
two SPDT (DG403) or two DPST (DG405) relay switch
contacts with CMOS or TTL level activation. The pinout is
similar, permitting a standard layout to be used, choosing the
switch function as needed.
