7.5 Noise Performance
Typical 0.1-Hz to 10-Hz voltage noise can be seen in Figure 26 . 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 26.
