THE PRECISION 12-BIT D/A CONVERTER REFERENCE

AD562, like most D/A converters, is designed to operate with a

+10 volt reference element. In the AD562, this 10 volt reference

voltage is converted into a reference current of approximately

0.5 mA via the internal 19.95 kΩ resistor (in series with the ex-

ternal 100 Ω trimmer). The gain temperature coefficient of the

AD562 is primarily governed by the temperature tracking of the

19.95 kΩ resistor and the 5k/10k span resistors; gain TC is

guaranteed to 3 ppm/°C. Thus, using the AD581L (at 5 ppm/°C)

as the 10 volt reference guarantees a maximum full-scale tem-

perature coefficient of 8 ppm/°C over commercial range. The 10

volt reference also supplies the normal 1 mA bipolar offset cur-

rent through the 9.95k bipolar offset resistor. The bipolar offset

TC thus depends only on TC matching of the bipolar offset

resistor to the input reference resistor and is guaranteed to

3 ppm/°C.
