... U APPLICATIONS INFORMATION Description The LTC1590 is a dual 12-bit multiplying DAC that has serial inputs and current outputs. It uses precision R/2R resistor ladder technology to provide exceptional linearity and stability. The device operates from a single 5V supply and provides a 10V reference input and voltage output range when used with an external op amp ...

... V ) OUT REF The LTC1590 can be used with a dual op amp to provide a dual 2-quadrant multiplying DAC as shown in Figure 2. The unipolar DAC transfer function is shown in Table 1. The 33pF feedback capacitor is recommended to compen- sate for the pole caused by the internal feedback resistor and the OUT1 output capacitance. For high speed op amps ...

... U APPLICATIONS INFORMATION Op Amp Selection To maintain the excellent accuracy and stability of the LTC1590 thought should be given to op amp selection. Fortunately, the sensitivity of INL and DNL to op amp offset has been significantly reduced compared to competing parts of this type. The op amp’ offset. In addition, because the DAC’s equivalent output ...
