Noise Performance

Typical 0.1-Hz to 10-Hz voltage noise for each member of the REF33xx family is specified in the Electrical Characteristics table. The noise voltage increases with output voltage and operating temperature. Use additional filtering to improve output noise levels. Give special attention to ensure that the output impedance does not degrade output voltage accuracy.
