AD584
The AD584 is normally used in the ?10 V mode with the AD7574
to give a 0 V to +10 V ADC range. This is shown in Figure 17.
Bipolar output applications and other operating details can be
found in the data sheets for the CMOS products.

scale temperature coefficient of 18 ppm/°C more than the
commercial range. The 10 V reference also supplies the normal
1 mA bipolar offset current through the 9.95 kΩ bipolar offset
resistor. The bipolar offset temperature coefficient thus depends
only on the temperature coefficient matching of the bipolar offset

PRECISION DAC REFERENCE
The AD565A , like many DACs, can operate with an external
10 V reference element (see Figure 19). This 10 V reference
voltage is converted into a reference current of approximately
0.5 mA via the internal 19.95 kΩ resistor (in series with the external

100 Ω trimmer). The gain temperature coefficient of the AD565A
is primarily governed by the temperature tracking of the 19.95 k?
resistor and the 5 kΩ/10 kΩ span resistors; this gain temperature
coefficient is guaranteed to 3 ppm/°C. Therefore, using the AD584 K
(at 5 ppm/°C) as the 10 V reference guarantees a maximum full-
