Voltage Reference Input
An external low-noise reference voltage must be applied to the
VREF pin to set the full-scale input range of the converter. The
reference input accepts voltages ranging from 0.1V to 2.2V for 3V
operation and 0.1V to 3.5V for 5V operation. The device is
specified with a reference voltage of 2.5V for 5V operation and
2.0V for 3V operation.
for the ISL267440/ISL26750A or ISL267817. Figure 30 uses the
precision ISL21090 voltage reference which exhibits
exceptionally low drift and low noise. The ISL21090 must use a
power supply greater than 4.7V. The VREF input pin of the
ISL267XX devices uses very low current, so the decoupling
capacitor can be small (0.1F).
Figure 31 illustrates the ISL21010 voltage reference being used
with these ADCs. The ISL21010 series voltage references have
higher noise and drift than the ISL26090 devices, but they
consume very low operating current and are excellent for
battery-powered applications.
