Overview
The DAC8562FSZ is a complete, parallel input, 12-bit, voltage output Digital-to-Analog Converter (DAC) designed and manufactured by Analog Devices Inc. This monolithic DAC operates from a single +5 volt supply and 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 self-contained solution for various applications. The reference output (REFOUT) is trimmed to 2.5 volts, and the on-chip amplifier scales the DAC output to 4.095 volts full scale. The DAC8562FSZ is coded in straight binary and features high-speed digital interface capabilities, allowing direct connection to fast processors without wait states.
