GENERAL DESCRIPTION
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.
