5 / 9 page  ZN428 Fig.4 shows equivalent circuit of the output (ignoring VOS). The output resistance R has a temperature coefficient of +0.2% per °C. The gain drift due to this is 0.2R % per °C. R+R L RL should be chosen as large as possible to make the gain drift small. As an example if RL = 400kΩ then the gain drift due to the T.C. of R for a 100 °C change in ambient temperature will be less than 0.2%. Alternatively the ZN428 can be buffered by an amplifier (see Operating Notes). REFERENCE (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 (RREF), should be connected between +VCC (pin 10) and pin 7. The recommended value of 390 Ω will supply a nominal reference current of (5.0- 2.5)/0.39 = 6.4mA. A stabilising/decoupling capacitor CREF = 1 µF is required between pins 7 and 8 for internal reference option, VREF OUT (pin 7) being connected to VREF IN (pin 6).
