The DACs are standard current output with separate VREF, IOUT1, IOUT2 and RFB terminals. The AD7568 is a serial input device. Data is loaded using FSIN , CLKIN and SDIN. One address pin, A0, sets up a de- vice address, and this feature may be used to simplify device loading in a multi-DAC environment. All DACs can be simultaneously updated using the asynchro- nous LDAC input and they can be cleared by asserting the asynchronous CLR input. The AD7568 is housed in a space-saving 44-pin plastic quad flatpack and 44-lead PLCC. Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties which may result from its use. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. REV. C One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A.
