GENERAL DESCRIPTION
The ADG1201/ADG1202 are monolithic complementary
metal-oxide semiconductor (CMOS) devices containing
an SPST switch designed in 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 perform-
ance 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.
The ultralow capacitance and charge injection of these
switches make them ideal solutions 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 parts suitable for video
signal switching.

Figure 1.
iCMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
The ADG1201/ADG1202 contain a single-pole/single-throw
(SPST) switch. Figure 1 shows that with a logic input of 1, the
switch of the ADG1201 is closed and that of the ADG1202 is
open. 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.
PRODUCT HIGHLIGHTS
1. Ultralow capacitance.
2. <1 pC charge injection.
3. Ultralow leakage.
4. 3 V logic-compatible digital inputs: VIH = 2.0 V, VIL = 0.8 V.
5. No VL logic power supply required.
6. SOT-23 package.
