The ADG1212-EP is a monolithic complementary metal-oxide
semiconductor (CMOS) device containing four independently
selectable switches designed on an iCMOS® (industrial CMOS)
process. iCMOS is a modular manufacturing process combining
high voltage CMOS and bipolar technologies. It enables the
development of a wide range of high performance analog ICs
capable of 33 V operation in a footprint that no previous generation
of high voltage parts has been able to achieve. Unlike analog
ICs using conventional CMOS processes, iCMOS components
can tolerate high supply voltages while providing increased
performance, dramatically lower power consumption, and
reduced package size.
FUNCTIONAL BLOCK DIAGRAM
1. SWITCHES SHOWN ARE
FOR LOGIC 1 INPUT.
The ultralow capacitance and charge injection of this switch
makes 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 makes
the part suitable for video signal switching.
iCMOS construction ensures ultralow power dissipation, making
the part ideally suited for portable and battery-powered instruments.
The ADG1212-EP contains four independent single-pole/
single-throw (SPST) switches. 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.
Additional application and technical information can be found
in the ADG1212 data sheet.
