Oct 20, 2015 · With an LM3886 the mute pin is connected to the -ve supply (usually via a resistor) to un-mute the output, but with the TDA7293 the mute pin is connected to a +ve voltage of 5V …

Jun 17, 2013 · Mute works by starving current fed to the LM3886 first stage, so to unmute you must turn this stage on. Since a grounded emitter PNP transistor controls this, you must feed …

TI’s LM3886 is a 68W, 1 Ch, 20-94V supply stereo Class-AB amplifier w/ Mute. Find parameters, ordering and quality information.

If customer worried about pop sound in Mute On/Off, I will recommend to use Cm. This mute operation is switched from signal pass Gm to Mute Gm when customer makes Mute mode …

Try a lower value resistor. My spreadsheet (trying to remember now how I set this up) seems to suggest that there's a 2.6V drop internally across the LM3886, and that a 68k resistor would …

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ωload and 38W into 8Ωwith 0.1% (THD + N) from 20 Hz–20 kHz.

I am using the LM3886 chips for an active speaker with logic operated mute control. Two LM3886 chips are used in each speaker, and I need to mute/unmute both chips simultaneously.
