Noise Performance

The REF30xx generates noise less than 50 μVPP between frequencies of 0.1 Hz to 10 Hz, and can be seen in Figure 20 The noise voltage of the REF30xx increases with output voltage and operating temperature. Additional filtering may be used to improve output noise levels; however, ensure the output impedance does not degrade AC performance.
