LM4766 volume is low

Hi,

I have connected a proper gain of  18k/1k i.e. gain of 18 but actually the output that i am getting is low..

The circuit works properly but the volume is low..

Please advice

  • Hi Aneesh,

    What is your load impedance?
    Are you using double o single supply? what voltage are you using?
    How low is it? Could you measure somehow the output?
    Could you share your schematic to look for any issue? You can send it to my e-mail address if you don't want to share it on a public forum: ivan.salazar@ti.com

  • Hi Aneesh, 

    Please check how you connected the Mute pin, as the mute pin is a current sense mode, so that you have to ensure that there is at least 0.5mA draw from the mute pin.
