AD7951BSTZ

AD7951 is a 14bit, charge redistribution, successive approximation register (SAR) architecture analogue-to-digital converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage process. The device is configured through hardware or via a dedicated write only serial configuration port for input range and operating mode. The AD7951 contains a high speed 14bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits and both serial and parallel system interface ports. Typical applications include process control, medical instruments, high speed data acquisition, digital signal processing, instrumentation, spectrum analysis and ATE.
