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 Ω) 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.
