Follow these general guidelines when designing the power supply:
- The power supply should be designed to provide the recommended operating conditions in terms of DC voltage, AC noise, and start-up ramp time.
- The maximum current draw for the LMH1218 is provided in the data sheet. This figure can be used to calculate the maximum current the supply must provide. Current consumption can be derived from the typical power consumption specification in the data sheet.
- The LMH1218 does not require any special power supply filtering, provided the recommended operating conditions are met. Only standard supply decoupling is required.
