Monolithic CMOS Analog Switches
Description
The DG401/883, DG403/883 and DG405/883 monolithic
CMOS analog switches have TTL and CMOS compatible
digital inputs.
These switches feature low analog ON resistance (<35鈩?
and fast switch time (t
ON
<150ns). Low charge injection sim-
pli鏗乪s sample and hold applications.
The improvements in the DG401/403/405/883 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 per-
mits controlling 30V peak-to-peak signals. Power supplies
may be single-ended from +5V to +34V, or split from
鹵5V
to
鹵17V.
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with ana-
log signals is quite low over a
鹵15V
analog input range. The
three different devices provide the equivalent of two SPST
(DG401/883), two SPDT (DG403/883) or two DPST
(DG405/883) 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.
