Exclamation Suggestion for Headphone AMP with MUTE

Hi Folks !

I'm using two LM1875 to drive three headphones, they are connected to the chipamp trought a 51R resistor each one, and the amp performance with Headphones is wonderful ! BUT...

I MUST have mute function. When the system starts, the circuitry makes noise, so the microcontroller must control the MUTE of amps, with a little delay on power. The power amp have it, and what should be a good replacement for Headphones amp with mute? No problems with LM1875 performance.

The amp will run on + / - 15v.

Thank you very much !


Best regards
