DESCRIPTION
The DG444B, DG445B are monolithic quad analog switches
designed to provide high speed, low error switching of
analog and audio signals. The DG444B, DG445B are
upgrades to the original DG444, DG445.
Combing low on-resistance (45 , typ.) with high speed
(tON 120 ns, typ.), the DG444B, DG445B are ideally suited
for Data Acquisition, Communication Systems, Automatic
Test Equipment, or Medical Instrumentation. Charge
injection has been minimized on the drain for use in
sample-and-hold circuits.
The DG444B, DG445B are built using Vishay Siliconix’s
high-voltage silicon-gate process. An epitaxial layer prevents
latchup.
When on, each switch conducts equally well in both
directions and blocks input voltages to the supply levels
when off.
