AD7656BSTZ

AD7656 is a 16bit fast, low power, successive approximation ADC. It is designed on the iCMOS™ process (industrial CMOS). iCMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. The conversion process and data acquisition are controlled using CONVST signals and an internal oscillator. Three CONVST pins allow independent, simultaneous sampling of the ADC. It has a high speed parallel and serial interface, allowing the device to interface with microprocessors or DSPs. In serial interface mode, the parts have a daisy-chain feature that allows multiple ADCs to connect to a single serial interface. It is widely used in application such as power line monitoring systems, instrumentation and control systems, multi-axis positioning systems etc.
