The DAC8512 is a complete serial input， 12-bit， voltage output digital-to-analog converter designed to operate from a single +5 V supply. It contains the DAC， input shift register and latches， reference and a rail-to-rail output amplifier. Built using a CBCMOS process， these monolithic DACs offer the user low cost， and ease of use in +5 V only systems. Coding for the DAC8512 is natural binary with the MSB loaded first. The output op amp can swing to either rail and is set to a range of 0 V to +4.095 V—for a one-millivolt-per-bit resolution. It is capable of sinking and sourcing 5 mA. An on-chip reference is laser trimmed to provide an accurate full-scale output voltage of 4.095 V. Serial interface is high speed， three-wire， DSP compatible with data in （SDI）， clock （CLK） and load strobe （LD）。 There is also a chip-select pin for connecting multiple DACs. A CLR input sets the output to zero scale at power on or upon user demand. The DAC8512 is specified over the extended industrial （–40°C to +85°C） temperature range. DAC8512s are available in plastic DIPs and SO-8 surface mount packages.
