Description
The DG201HS is an improved monolithic device
containing four independent analog switches. It is
designed to provide high speed, low error switching of
analog signals. Combining low on-resistance (25
W)
with
high speed (t
ON
: 38 ns), the DG201HS is ideally suited for
high speed data acquisition requirements.
To achieve high voltage ratings and superior switching
performance, the DG201HS is built on a proprietary
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 values,
when off.
