Overview
The AD8582AR, produced by Analog Devices Inc., is a complete, parallel input, dual 12-bit digital-to-analog converter (DAC) designed to operate from a single +5 volt supply. This monolithic DAC, built using a CBCMOS process, offers low cost and ease of use in +5 volt only systems. It includes on-chip components such as a rail-to-rail amplifier, latch, and reference, making it a comprehensive solution for various applications. The reference voltage (VREF) is trimmed to 2.5 volts, and the on-chip amplifier scales the DAC output to 4.095 volts full scale. The AD8582AR is coded in natural binary and features a high-speed parallel data interface, allowing it to connect to the fastest processors without wait states.
