GENERAL DESCRIPTION

The ADG1401/ADG1402 contain a single-pole/single-throw

(SPST) switch. Figure 1 shows that with a logic input of 1, the

switch of the ADG1401 is closed and that of the ADG1402 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.

The iCMOS® (industrial CMOS) modular manufacturing process

combines high voltage, complementary metal-oxide semiconductor

(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 other generation of high voltage

parts has achieved. Unlike analog ICs using conventional CMOS

processes, iCMOS components can tolerate high supply voltages

while providing increased performance, dramatically lower

power consumption, and a reduced package size.

The on resistance profile is very flat over the full analog input

range ensuring excellent linearity and low distortion when

switching audio signals. The iCMOS construction ensures

ultralow power dissipation, making the part ideally suited for

portable and battery-powered instruments.
