Because of this relationship, acceptable load current in high temperature conditions may be less than the

maximum current-sourcing capability of the device. In no case should the device be operated outside of its

maximum power rating because doing so can result in premature failure or permanent damage to the device.

8.5 Noise Performance

Typical 1/f noise (0.1-Hz to 10-Hz) can be seen in Figure 8-3. Device noise increases with output voltage and

operating temperature. Typically 1/f noise is not practical to filter out which makes it a key parameter for ultra-low

noise measurements. Additional filtering can be used to improve broadband noise output noise levels, although

care must be taken to ensure the output impedance does not degrade ac performance.
