9 Power Supply Recommendations

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 and maximum current consumption.
  • The maximum current draw for the LMH0387 is provided in the data sheet. This number can be used to calculate the maximum current the supply must provide.
  • The LMH0387 does not require any special power supply filtering, provided the recommended operating conditions are met. Use 0.1-µF capacitors as close to the device VCCRX and VCCTX pins as possible.
