Description

The DG202/DG212 are normally open, quad single-polesingle-throw (SPST) analog switches. TheseCMOS switches can be continuously operated withpower supplies ranging from ±4.5V to ±18V. Maximguarantees that these switches will not latch up if thepower supplies are disconnected with input signals stillconnected.The DG202/DG212 are similar to the DG201/DG211except for inverted control inputs. All devices haveguaranteed break-before-make switching, as well asessentially constant on-resistance over the analogsignal range. All switches conduct current in eitherdirection and add no offset to the output signal.Compared to the original manufacturer's products,Maxim's DG202/DG212 consume very little power,making them better suited for portable applications.Maxim has also eliminated the need for the third logicpower supply (VL) that is required for the operation ofthe original manufacturer's DG212 without sacrificingcompatibility.ApplicationsAnalog MultiplexersAutomatic Test EquipmentCommunication SystemsPBX, PABXProgrammable Gain AmplifiersSample/Holds
