Although there is any input singal,it still generate 40KHZ modulating wave output.
Could tell me what could cause this? How can i solve this problem? Testing method as fellow: Power Supply: 24V/4Ohm test load: cement resistor(4Ohm/100W) #tda7498-modulating-wave-output2014-09-09 09:22 PM

Hi Zhao
Thanks for your so quickly and professional reply.I attached my wave picture,is this noise voltage? If so could you give me some advice how to improve it. Thanks!2014-09-09 11:26 PM
