General Description
Maxim's DG300DG303 and DG300ADG303A CMOS
dual and quad analog switches combine low power
operation with fast switching times and superior DC and
AC switch characteristics. On-resistance is less than
50
and is essentially constant over the analog signal
range. Device specifications are ideal for battery-
powered circuitry.
These switches are available in a variety of formats as
outlined in the Pin Configurations section. The switch
control logic inputs are fully TTL and CMOS compati-
ble. Also featured are "break-before-make" switching
and low charge injection.
Maxim's DG300-DG303 and DG300A-DG303A families
are electrically compatible and pin compatible with the
original manufacturer's devices. All devices operate with
power supplies ranging from 5V to 18V. Single-sup-
ply operation is implemented by connecting V- to GND.
Applications
