The DG411/883 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 compat-
ible digital inputs.
These switches feature lower analog ON resistance (<35Ω)
and faster switch time (t_ON <175ns) compared to the DG211
or DG212. Charge injection has been reduced, simplifying
sample and hold applications.
The improvements in the DG411/883 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_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 ±15V analog input range. The
switches in the DG411/883 and DG412/883 are identical, dif-
fering only in the polarity of the selection logic. Two of the
switches in the DG413/883 (#1 and #4) use the logic of the
DG211 and DG411/883 (i.e. a logic “0” turns the switch ON)
and the other two switches use DG212 and DG412/883 posi-
tive logic. This permits independent control of turn-on and
turn-off times for SPDT configurations, permitting “break-
before-make” or “make-before-break” operation with a mini-
mum of external logic.
