AD8582ARZ

AD8582 is a complete, parallel input, dual 12bit, voltage output DAC designed to operate from a single +5 volt supply. Built using a CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in +5V only systems. Included on the chip, in addition to the DACs, are a rail-to-rail amplifier, latch and reference. The reference (VREF) is trimmed to 2.5V output, and the on-chip amplifier gains up the DAC output to 4.095V full scale. The high speed parallel data interface connects to the fastest processors without wait states. The double-buffered input structure allows the user to load the input registers one at a time, then a single load strobe tied to both LDA + LDB inputs will update both DAC outputs simultaneously. LDA and LDB can also be activated independently to update their respective DAC registers immediately. Application includes digitally controlled calibration, portable equipment, servo controls, process control equipment, PC peripherals.
