Part Number: OPA855

I want to use operational amplifier OPA855 as output device to antenna 50 ohm. What is the maximum power that I can get from amplifier staying in linear mode.
Thank,
Martin, RF Engineer.

Hi Martin,

what frequency are we speaking about? Can you show a schematic?

Hello Martin,

The linear output drive of the device at 25 C is rated up to 80mA. According to figures 37 & 38 in the datasheet, the amplifier can sink around 0.9V and source 1V from mid-supply under the test conditions specified.

Best,

Hasan Babiker
