AD7568

a LC2MOS Octal 12-Bit DAC AD7568 FEATURES Eight 12-Bit DACs in One Package 4-Quadrant Multiplication Separate References Single +5 V Supply Low Power: 1 mW Versatile Serial Interface Simultaneous Update Capability Reset Function 44-Pin PQFP and PLCC APPLICATIONS Process Control Automatic Test Equipment General Purpose Instrumentation GENERAL DESCRIPTION The AD7568 contains eight 12-bit DACs in one monolithic device. 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 device address, and this feature may be used to simplify device loading in a multi-DAC environment. All DACs can be simultaneously updated using the asynchronous 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. FUNCTIONAL BLOCK DIAGRAM VDD AGND DGND VREFD VREFC ...
