Overview
The DAC8562FSZ-REEL, produced by Analog Devices Inc., is a complete, parallel input, 12-bit digital-to-analog converter (DAC) designed to operate from a single +5 volt supply. This monolithic DAC is built using a CBCMOS process, offering low cost and ease of use in +5 volt only systems. The device includes a rail-to-rail amplifier, latch, and reference on the chip, making it a ready-to-use solution for various applications. The reference voltage (REFOUT) is trimmed to 2.5 volts, and the on-chip amplifier scales the DAC output to 4.095 volts full scale. The DAC8562 is coded in straight binary and features a high-speed parallel digital interface that can interface with the fastest processors without wait states.
