... FPO FPO 41% resistors, as well as low integral and differential lin- earity errors. Innovative circuit design enables the DAC80 to operate at supply voltages as low as 11.4V with no loss in performance or accuracy over any = 12VDC range of output voltage. The lower power dissipation of this 118-mil by 121-mil chip results in higher reliability and greater long term stability ...

... C (ppm/ C). Gain drift is established by: 1) testing the end point differences for each DAC80 model +25 C, and + calculating the gain error with respect to the 25 C value, and; 3) dividing by the temperature change. This figure is expressed in ppm/ C and is given in the electrical specifications both with and without internal reference ...

... FIGURE 4. Equivalent Resistances. Existing applications that are converting to the monolithic DAC80 must change the gain trim resistor on pin 23 from 33M to 10M to insure sufficient adjustment range. Pin high impedance point and a 0.001 1F to 0.01 F ceramic capacitor should be connected from this pin to Common (pin 21) to prevent noise pickup ...
