Overview
The DAC8562FS is a 12-bit, parallel input, voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is designed to operate from a single +5 volt supply, making it highly suitable for systems that require simplicity and ease of use. The DAC8562FS includes a rail-to-rail amplifier, a latch, and an internal reference, which is trimmed to 2.5 volts. The on-chip amplifier amplifies the DAC output to a full-scale voltage of 4.095 volts. The device is coded in straight binary and features a high-speed digital interface that can interface directly with fast processors without wait states.
