AD7549JNZ

AD7549 is a monolithic dual, 12bit, current output D/A converter. Both DACs provide four quadrant multiplication capabilities with a separate reference input and feedback resistor for each DAC. The monolithic construction ensures excellent thermal tracking and gain error tracking between the two DACs. The DACs in the AD7549 are each loaded in three 4-bit nibbles. The control logic is designed for easy processor interfacing. Input and DAC register loading is accomplished using address lines AO, Al, A2 and CS, WR lines. A logic high level on the CLR input clears all registers. Both DACs may be simultaneously updated using the UPD input. Typical applications include programmable filters, automatic test equipment, microcomputer-based process control, audio systems, programmable power supplies and Synchro applications.
