Because the LMP91050 is used in a sampled data system, care must be taken to maintain power supply noise below an acceptable level, which will depend on the requirements of the application. In all cases, follow the manufacturer’s design recommendations for the power conditioning device used in the system. The LMP91050 offers excellent power supply rejection over a wide range of frequencies, but adequate power supply bypassing should always be used (see Figure 26). If using a switching supply, additional filtering may be required particularly if the switcher harmonics fall within the passband of the filters used in the system. Ensure that the selected power conditioning device is capable of sourcing the current required by the LMP91050.
