8.3 Noise Performance

Typical 0.1-Hz to 10-Hz voltage noise can be seen in Figure 17. 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 17.
