8.3 Noise Performance

Typical 0.1-Hz to 10-Hz voltage noise is shown in Figure 41 and Figure 42. Device noise increases with output

voltage and operating temperature. Additional filtering can be used to improve output noise levels, although care

must be taken to ensure the output impedance does not degrade ac performance. Peak-to-peak noise

measurement setup is shown in Figure 43.
