Posted on January 07, 2016 at 11:04Hi,I am using STA321MP to record the audio signal, I have observed the noise from its output signal when there is no speech. The period is ~20ms. Do you have any idea where it is from?
Posted on January 07, 2016 at 16:44hi, boys.I bought 100 TDA7297 and ran only 2. I wonder if there might be fakes in the market for this Amp Model , or if there is another version that works with other than the proposed schematic datasheet . Someone...
Posted on December 15, 2015 at 07:57Hi, Can i use single output only with stereo output provision? for eg: TDA7297 is 2+15W stereo IC, But i want single (mono) out only with 15W, Can i use single channel only? reaming channel should connect or m...
