NOISE PERFORMANCE

Typical 0.1Hz to 10Hz voltage noise for each member of the REF50xx family is specified in the Electrical

Characteristics: Per Device table. The noise voltage increases with output voltage and operating temperature.

Additional filtering can be used to improve output noise levels, although care should be taken to ensure the

output impedance does not degrade performance.

For additional information about how to minimize noise and maximize performance in mixed-signal applications

such as data converters, refer to the series of Analog Applications Journal articles entitled, How a Voltage

Reference Affects ADC Performance. This three-part series is available for download from the TI website under

three literature numbers: SLYT331, SLYT339, and SLYT355 for Part I, Part II, and Part III, respectively.
