Monolithic Quad SPST CMOS Analog Switches
Description
The DG441/883 and DG442/883 monolithic CMOS analog
switches are drop-in replacements for the popular DG201A/
883 and DG202/883 series devices. They include four inde-
pendent single pole single throw (SPST) analog switches,
TTL and CMOS compatible digital inputs, and a voltage ref-
erence for logic thresholds.
These switches feature lower analog ON resistance (<85鈩?
and faster switch time (t
ON
<250ns) compared to the
DG201A/883 and DG202/883. Charge injection has been
reduced, simplifying sample and hold applications.
The improvements in the DG441/883 series are made possi-
ble 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 con-
trolling 40V peak-to-peak signals. Power supplies may be
single-ended from +5V to +34V, or split from
鹵5V
to
鹵20V.
The four switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with analog
signals is quite low over a
鹵5V
analog input range. The
switches in the DG441/883 and DG442/883 are identical, dif-
fering only in the polarity of the selection logic.
