AD7548JNZ Datasheet PDF - ADI

●The AD7548JNZ is a 12-bit monolithic CMOS Digital-to-analog Converter (DAC) for use with 8-bit bus microprocessors. Data is loaded in 2 bytes to input holding registers. The AD7548 can be configured to accept either left- or right-justified data, least significant byte or most significant byte first, using standard TTL compatible control inputs. A separate load DAC control input allows the user the choice of updating the analog output coincident with loading new data to the DAC input register or at any time after the data loading event. This feature is especially important in multi-DAC systems where simultaneous update of DAC is required. The new linear compatible CMOS process used in the manufacture of the AD7548 allows precision thin-film linear circuitry and high speed low power CMOS logic to be integrated on the same small chip. The high speed logic allows direct interfacing to most of the popular 8-bit microprocessors.
