General Description

Maxim’s DG300–DG303 and DG300A–DG303A 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

Ω 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.
