overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or
earphone amplifier.
• The power supply input cables should be kept separate from noise sensitive lines
such as microphone/earphone cables.
• The insertion of EMI filter on VBATT pins is suggested in those designs where
antenna is placed close to battery or supply lines. A ferrite bead like Murata
BLM18EG101TN1 or Taiyo Yuden P/N FBMH1608HM101 can be used for this
purpose.
The below figure shows the recommended circuit:
