GENERAL DESCRIPTION
The ADG1517 is a single-pole/single-throw (SPST) switch.
Figure 1 shows that with a logic input of 1, the switch of the
ADG1517 is closed. The 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 CMOS (complementary metal-oxide
semiconductor) and bipolar technologies. It enables the develop-
ment of a wide range of high performance analog ICs in a footprint
that no other 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 on resistance profile is very flat over the full analog input
range, ensuring excellent linearity and low distortion when
switching audio signals. iCMOS construction ensures ultralow
power dissipation, making the part ideally suited for portable
and battery-powered instruments.
