7.4 Noise Performance

Figure 7-7 and Figure 7-8 show typical 0.1Hz to 10Hz voltage noise. Device noise increases with output voltage and operating temperature. Use additional filtering to improve output noise levels. Verify that the output impedance does not degrade AC performance. Peak-to-peak noise measurement setup is shown in Figure 7-9.
