Part Number: LM48511

hi TIer,

    Could you please help to check if LM48511 can drive 8Ω 1.5W speaker and how to set the parameter of LM48511,TKS.

  • Hi Jerry,

    Data sheet specifies that LM48511 is able to output 3W into 8ohm load at 1% THD+N when powered by 5V.
    LM48511 is an analog input amplifier and hardware controlled; what parameters are you asking for? You can use the recommended component values from typical application circuit, and also check section 8.2.2 if you want to select different component values.
