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 plas- tic DIPs and SO-8 surface mount packages. 1.0 –1.0 4096 –0.5 –0.75 0 0 –0.25 0.25 0.5 0.75 3072 2048 1024 DIGITAL INPUT CODE – Decimal Linearity Error vs. Digital Input Code |
