GENERAL DESCRIPTION
The ADG1236 is a monolithic CMOS device containing two
independently selectable SPDT switches. It is designed on an
iCMOS
process.
iCMOS
(industrial-CMOS) is a modular
manufacturing process combining high voltage CMOS
(complementary metal-oxide semiconductor) and bipolar
technologies. It enables the development of a wide range of high
performance analog ICs capable of 30 V operation in a footprint
that no previous generation of high voltage parts has been able
to achieve. Unlike analog ICs using conventional CMOS proc-
esses,
iCMOS
components can tolerate high supply voltages,
while providing increased performance, dramatically lower
power consumption, and reduced package size.
The ultralow capacitance and charge injection of the part make
it an ideal solution for data acquisition and sample-and-hold
applications, where low glitch and fast settling are required. Fast
switching speed coupled with high signal bandwidth make the
part suitable for video signal switching.
iCMOS
construction
ensures ultralow power dissipation, making the part ideally
suited for portable and battery-powered instruments.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. In the
off condition, signal levels up to the supplies are blocked. Both
switches exhibit break-before-make switching action for use in
multiplexer applications.
