8.3 Noise Performance

Typical 0.1-Hz to 10-Hz voltage noise can be seen in Figure 45 and Figure 46. Device noise 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 ac performance. Peak-to-peak

noise measurement setup is shown in Figure 47.
