APPLICATIONS
Automatic test equipment
Data acquisition systems
Battery-powered systems
Sample-and-hold systems
Audio signal routing
iCMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
Video signal routing
Communication systems
The ADG1211/ADG1212/ADG1213 contain four independent
single-pole/single-throw (SPST) switches. The ADG1211 and
ADG1212 differ only in that the digital control logic is inverted.
The ADG1211 switches are turned on with Logic 0 on the
appropriate control input, while Logic 1 is required for the
ADG1212. The ADG1213 has two switches with digital control
logic similar to that of the ADG1211; the logic is inverted on
the other two switches. The ADG1213 exhibits break-before-
make switching action for use in multiplexer applications.
GENERAL DESCRIPTION
The ADG1211/ADG1212/ADG1213 are monolithic complemen-
tary metal-oxide semiconductor (CMOS) devices 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.
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.
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.
2. <1 pC charge injection.
3. 3 V logic-compatible digital inputs: VIH = 2.0 V, V IL = 0.8 V.
4. No VL logic power supply required.
5. Ultralow power dissipation: <0.03 µW.
6. 16-lead TSSOP and 3 mm × 3 mm LFCSP packages.
