Monolithic, Quad SPST, CMOS Analog
Switches
The DG441 and DG442 monolithic CMOS analog switches
are drop-in replacements for the popular DG201A and
DG202 series devices. They include four independent single
pole single throw (SPST) analog switches, TTL and CMOS
compatible digital inputs, and a voltage reference for logic
thresholds.
These switches feature lower analog ON resistance (<85Ω)
and faster switch time (t_ON < 250ns) compared to the
DG201A and DG202. Charge injection has been reduced,
simplifying sample and hold applications.
The improvements in the DG441 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 40V_P-P signals. Power supplies may be single-
ended from +5V to +34V, or split from ±5V to ±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 ±5V analog input range.
The switches in the DG441 and DG442 are identical,
differing only in the polarity of the selection logic.
