LM4952: 64ohms capability

Part Number: LM4952

Hi Audio team,

My customer is considering to use LM4952 as 64ohms headphone amp driver.
Do you have any data with 64ohms load with following condition?
> 12Vdd, 10/20% THD+N

In addition, is it ok to use LM4952 as 64ohms headphone amp?


  • Hi Kai

    You can use 64 ohm loads, this should not cause issues. You should consider that increased impedance would reduce output power.
    Unfortunately there is no data available for 64 ohm loads.
