General Description

The DG202/DG212 are normally open, quad single-

pole single-throw (SPST) analog switches. These

CMOS switches can be continuously operated with

power supplies ranging from ±4.5V to ±18V. Maxim

guarantees that these switches will not latch up if the

power supplies are disconnected with input signals still

connected.

The DG202/DG212 are similar to the DG201/DG211

except for inverted control inputs. All devices have

guaranteed break-before-make switching, as well as

essentially constant on-resistance over the analog

signal range. All switches conduct current in either

direction 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 logic

power supply (V

) that is required for the operation of

the original manufacturer’s DG212 without sacrificing

compatibility.
