GENERAL DESCRIPTION
The ADG1419 is a monolithic iCMOS® device containing a
single-pole/double-throw (SPDT) switch. An EN input on the
LFCSP package is used to enable or disable the device. When
disabled, all channels are switched off.
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 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.
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
ADG1419 exhibits break-before-make switching action for use
in multiplexer applications.
