Hai all, I am facing an issue related with power amplifier design. I am designing an amplifier with apex PA02 IC (50W Class AB) the problem is when i am working with lower frequencies (less than100kz) (Input voltage is sine 1 Volt peak to peak ) it is working fine but when i am increasing frequency like about 200khz the output wave is distorting. Supply voltage is 12vdc and load resistance is 500R. IC Data sheet saying band width of 350Khz and slew rate of 20V/uS. On my observation i found that when i reduce the input voltage to 0.5 volt pk to pk the output can vary up to 250 Khz without much distortion. Here i am attaching circuit diagram and distorted wave forms Please help me
Thank in advance
