... Reduced values of reference voltage will also permit the 12 volt 5% power supply requirement to be relaxed to 12 volts 10 not recommended that the AD767 be used with external feedback resistors to modify the scale factor. The internal resistors are trimmed to ratio-match and temperature-track the other resistors on the chip, even though their absolute tolerances are 20%, and absolute temperature coefficients are approximately – ...

... It is also important to apply decoupling capacitors properly on the power supplies for the AD767. The correct method for decoupling is to connect a capacitor from each power supply pin of the AD767 to the analog ground pin of the AD767. Any load driven by the output amplifier should also be referred to the analog ground pin. ...

... Interfacing the AD767 to the 8086 16-bit microprocessor requires a minimal amount of external components MHz 8086, for example, generates a 165 ns low write pulse which may be gated with a decoded address to provide CS for the AD767 returns high valid data is latched into the DAC. See Figure ...
