DESCRIPTION

•

Reduced power supply requirements

Faster throughput

The DG444, DG445 monolithic quad analog switches are

designed to provide high speed, low error switching of analog

signals. The DG444 has a normally closed function. The

DG445 has a normally open function. Combining low power

(22 nW, typ) with high speed (t_ON: 120 ns, typ.), the DG444,

DG445 are ideally suited for upgrading DG211, DG212

sockets. Charge injection has been minimized on the drain

for use in sample-and-hold circuits.

Improved reliability

Reduced pedestal errors

• Simple interfacing

To achieve high-voltage ratings and superior switching

performance, the DG444, DG445 are built on Vishay

Siliconix’s high-voltage silicon-gate process. An epitaxial

layer prevents latchup.

Each switch conducts equally well in both directions when

on, and blocks input voltages to the supply levels when off.
