How to set DA14585 ouput power by software

Hello Dialog,
What is the output power range of the DA14585? Is it adjustable? If it is adjustable, how can I achieve this through software?

best regards

Hi Edwin An,

Hi Edwin An,

According to DA14585 datasheet:

  • TX: 3.4 mA, RX: 3.7 mA (with ideal DCDC)
  • 0 dBm transmit output power
  • -20 dBm output power in “Near Field Mode”
  • -93 dBm receiver sensitivity

有一个参考性用途e design named Range extender and you could have increased transmit output power:

  • Up to +9.3 dBm Nominal Maximum Output Power
  • Better than -91 dBm receive sensitivity
  • Tx <17 mA system peak @ 3 V @ +9.3 dBm Nominal Maximum Output Power

Please have a look at this design in or support website:

Thanks, PM_Dialog
