should be chosen as large as possible to make the
gain drift small. As an example if R
drift due to the T.C. of R for a 100
temperature will be less than 0.2%. Alternatively the ZN428
can be buffered by an amplifier (see Operating Notes).

(a) Internal Reference
The internal reference is an active bandgap circuit which
is equivalent to a 2.5V Zener diode with very low slope
impedance (Fig.5). A resistor (R
between +V
CC
(pin 10) and pin 7. The recommended value
of 390
will supply a nominal reference current of (5.0-
2.5)/0.39 = 6.4mA. A stabilising/decoupling capacitor C
