MAXIM DG202, DG212 User Manual

General Description

The DG202/DG212 are normally open, quad single­pole 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 (VL) that is required for the operation of
the original manufacturer’s DG212 without sacrificing
compatibility.
