AD581
10 V reference guarantees a maximum full-scale temperature
coefficient of 8 ppm/°C over the commercial range. The 10 V
reference also supplies the normal 1 mA bipolar offset current
through the 9.95 kΩ bipolar offset resistor. Consequently, the
bipolar offset TC depends only on TC matching of the bipolar
offset resistor to the input reference resistor and is guaranteed
to 3 ppm/°C.
