GENERAL DESCRIPTION AD7658BSTZ

The AD7656/AD7657/AD76581 contain six 16-/14-/12-bit,

fast, low power, successive approximation ADCs all in the one

package that is designed on the iCMOS™ process (industrial

CMOS). iCMOS is a process combining high voltage silicon

with submicron CMOS and complementary 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

could achieve. Unlike analog ICs using conventional CMOS

processes, iCMOS components can accept bipolar input signals

while providing increased performance, which dramatically

reduces power consumption and package size.
