分享资料个
The AD7951 is a 14-bit， charge redistribution， successive approximation register （SAR） architecture analog-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 14-bit sampling ADC， an internal conversion clock， an internal reference （and buffer）， error correction circuits， and both serial and parallel system interface ports. A falling edge on CNVST samples the analog input on IN+ with respect to a ground sense， IN−。 The AD7951 features four different analog input ranges and three different sampling modes： warp mode for the fastest throughput， normal mode for the fastest asynchronous throughput， and impulse mode where power is scaled with throughput. Operation is specified from −40°C to +85°C.
