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.

75 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.
