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.
