    LM4876MX audio amplifier oscillation problem

    Thanks for the response. The bypass caps are in place. I found the source of the severity of the oscillations. There were 1nF ESD caps to GND connected to each output pad (pads 5 and 8), leftover from previous design. W/o it the oscillation stopped but the signal was distorted at the "cross over...

    LM4876MX audio amplifier oscillation problem

    I have oscillation problem (at ~5MHz!) with LM4876 "differential" audio amplifier. It seems to stem from stability issues at "zero crossing" level. One aspect of it is that driving it with high frequency input signal (few hundreds of KHz, removing the low pass feedback capacitor), the zero...
