Monolithic, Quad SPST, CMOS Analog

Switches

Features

• ON Resistance (Max). . . . . . . . . . . . . . . . . . . . . . . . . 85Ω

The DG444 and DG445 monolithic CMOS analog switches

are drop-in replacements for the popular DG211 and DG212

series devices. They include four independent single pole

single throw (SPST) analog switches and TTL and CMOS

compatible digital inputs.

• Low Power Consumption (P ) . . . . . . . . . . . . . . . . <35µW

OFF

• Low Charge Injection

These switches feature lower analog ON resistance (<85Ω)

and faster switch time (t

and DG212. Charge injection has been reduced, simplifying

sample and hold applications.

<250ns) compared to the DG211

• Upgrade from DG211/DG212

• TTL, CMOS Compatible

• Single or Split Supply Operation

The improvements in the DG444 series are made possible

by using a high voltage silicon-gate process. An epitaxial

layer prevents the latch-up associated with older CMOS

technologies. The 44V maximum voltage range permits

controlling ±20V signals when operating with ±20V power

supplies.

Applications

• Audio Switching

• Battery Operated Systems

• Data Acquisition

The four switches are bilateral, equally matched for AC or

bidirectional signals. The ON resistance variation with

analog signals is quite low over a ±5V analog input range.

The switches in the DG444 and DG445 are identical,

differing only in the polarity of the selection logic.

• Hi-Rel Systems

• Sample and Hold Circuits

• Communication Systems

• Automatic Test Equipment
