SBVS299A April 2017 – September 2025 REF31-Q1
PRODUCTION DATA
Typical 0.1-Hz to 10-Hz voltage noise can be seen in Figure 7-2. The noise voltage of the REF31xx-Q1 increases with output voltage and operating temperature. Additional filtering may be used to improve output noise levels, although take care to ensure the output impedance does not degrade the AC performance.
