AD569
Figures 11, 12, and 13 show reference configurations for various
output ranges. As shown in Figure 11, the pin-programmable
AD588 can be connected to provides tracking 5 V outputs
with 1-3ppm/ C temperature stability. Buffer amplifiers are in-
cluded for direct connection to the AD569. The optional gain
and balance adjust trimmers allow bipolar offset and full-scale
errors to be nulled. In Figure 12, the low-cost AD586 provides

+5 V reference. A dual op amp, the AD712, buffers the refer-
ence input terminals preserving the absolute accuracy of the
AD569. The optional noise-reduction capacitor and gain
adjust trimmer allow further elimination of errors. The low-
cost AD584 offers 2.5 V, 5 V, 7.5 V, and 10 V options and
can be connected for 5 V tracking outputs as shown in Figure
13. Again, an AD712 is used to buffer the reference input
terminals.
