Monolithic Quad SPST, CMOS AnalogSwitches

The DG411 series monolithic CMOS analog switches aredrop-inreplacements for the popular DG211 and DG212series devices. They include four independent single polethrow (SPST) analog switches, and TTL and CMOScompatible digital inputs.

These switches feature lower analog ON resistance (<35 )and faster switch time (tON < 175ns) compared to theDG211 or DG212. Charge injection has been reduced,simplifying sample and hold applications.

The improvements in the DG411 series are made possibleby using a high voltage silicon-gate process. An epitaxiallayer prevents the latch-up associated with older CMOStechnologies. The 44V maximum voltage range permitscontrolling 40VP-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 orbidirectional signals. The ON resistance variation with

analog signals is quite low over a ±15V analog input range.The switches in the DG411 and DG412 are identical,

differing only in the polarity of the selection logic. Two of theswitches in the DG413 (#1 and #4) use the logic of the

DG211andDG411(i.e.,alogic“0”turnstheswitchON)andtheothertwoswitchesuseDG212andDG412positivelogic.This permits independent control of turn-on and turn-offtimes for SPDT con gurations, permitting “break-before-make” or “make-before-break” operation with a minimum ofexternal logic.
