Figure shows the AD585 used in A / D Conversion System circuit . AD585 has a fast sampling time , it can be used for multi-channel data acquisition system , complete high-frequency signal and high pass rate of high-speed A / D transformation . AD585 Sample and Hold signals the completion of the work , AD578K ADC signals the completion of the task . 0 ~ 10V analog signal input from the AD585 's 2 feet , 8 feet after the sample and hold output to AD578K of 27 feet , after AD578K 12bit analog signal into digital signal output . Sample and hold the STATUS state by the end of AD578K (20 feet ) output control signals to the AD585 's HOLD side (12 feet ) to complete . When HOLD = 0 , the circuit is sampling state ; when HOLD = 1 , the circuit is on hold. Signals through the rate of 117.6kHz, the maximum input frequency of 58.8kHz.
