Rev 10.00
Nov 20, 2006 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 (<85пЃ—)
and faster switch time (tON <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 40VP-P signals. Power supplies may be single
ended from +5V to +34V, symmetrical supplies from В±5V to
В±22V or asymmetrical supplies limited to a maximum
differential voltage of 44V with a V+ max of 34V or a V-max
of -25V. …
