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.
