DESCRIPTION
The DG441B/442B are monolithic quad analog switches
designed to provide high speed, low error switching of analog
and audio signals. The DG441B/442B are upgrades to the
original DG441/442.
Combing low on-resistance (45
(t
ON
120 ns, typ.), the DG441B/442B are ideally suited for
Data Acquisition, Communication Systems, Automatic Test
Equipment, or Medical Instrumentation. Charge injection has
, typ.) with high speed
been minimized on the drain for use in sample-and-hold
circuits.
The DG441B/442B 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.
