DESCRIPTION
The DG441B, DG442B are monolithic quad analog switches
designed to provide high speed, low error switching of
analog and audio signals. The DG441B, DG442B are
upgrades to the original DG441, DG442.
Combing low on-resistance (45 , typ.) with high speed
(tON 120 ns, typ.), the DG441B, DG442B 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 DG441B, DG442B 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.
