Overview
The DAC8512FSZ is a complete serial input, 12-bit, voltage output digital-to-analog converter (DAC) designed by Analog Devices Inc. This monolithic DAC operates from a single +5V supply and includes the DAC, input shift register and latches, reference, and a rail-to-rail output amplifier. Built using a CBCMOS process, it offers low cost and ease of use in +5V only systems. The device is widely used in various applications due to its high-speed, three-wire serial interface that is DSP compatible.
