2.4 Best Practices

• Use the power supply which has very good PSRR.
• Measure the output with high resolution instrument (DMM, oscilloscope) for best performance.
• Connect J4 VREF out to data converter EVM for best performance.
• Wait to begin measuring at least until the output voltage has settled and the LED has turned off, representing
that REF80 internal heater temperature is now stable.
