June 20, 2007 Monolithic Quad SPST, CMOS Analog Switches
The DG411 series monolithic CMOS analog switches are
drop-in replacements for the popular DG211 and DG212
series devices. They include four independent single pole
throw (SPST) analog switches, and TTL and CMOS
compatible digital inputs.
These switches feature lower analog ON-resistance (<35пЃ—)
and faster switch time (tON<175ns) compared to the DG211
or DG212. Charge injection has been reduced, simplifying
sample and hold applications.
The improvements in the DG411 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 44V, or split from В±5V to В±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 В±15V analog input range. The
switches in the DG411 and DG412 are identical, differing only …
