Overview
The DAC8512FSZ-REEL, manufactured by Analog Devices Inc., is a complete serial input, 12-bit, voltage output digital-to-analog converter (DAC). Designed to operate from a single +5 V supply, it integrates the DAC, input shift register and latches, reference, and a rail-to-rail output amplifier. Built using a CBCMOS process, this monolithic DAC offers low cost and ease of use in +5 V only systems. The device is coded in natural binary with the MSB loaded first and features an output range of 0 V to +4.095 V, providing a one-millivolt-per-bit resolution.
