9.4.1 Layout Guidelines

  • Place the power-supply bypass capacitor as close as possible to the supply and ground pins. The recommended value of this bypass capacitor is from 0.1μF to 10μF. If necessary, additional decoupling capacitance can be added to compensate for noisy or high-impedance power supplies. The smallest capacitor must be placed closest to the device.
  • The output must be decoupled with a 1μF to 100μF low ESR (maximum 1Ω) capacitor.
  • Place a 1μF to 100μF low leakage noise filtering capacitor between the NR pin and ground.
