AD7657BSTZ-1

AD7657-1 is a six channel, 14-bit, fast, low power successive approximation ADC. 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 analogue ICs capable of 33V operation in a footprint that no previous generation of high voltage parts could achieve. The conversion process and data acquisition are controlled using the CONVST signals and an internal oscillator. Three CONVST pins (CONVST A, CONVST B, and CONVST C) allow independent, simultaneous sampling of the ADC pairs. This device has a high speed parallel and serial interface, allowing the device to interface with microprocessors or DSPs. It is widely used in application such as power line monitoring and measuring systems, instrumentation and control systems, multi axis positioning systems etc.
