GENERAL DESCRIPTION
The AD7324 is a 4-channel, 12-bit plus sign, successive approximation ADC designed on the i
CMOS (industrial
CMOS) process. i
CMOS 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, i
CMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption, and reduced package size. The AD7324 can accept true bipolar anal...
