Re: Creative Sound Blaster 16s with incorrectly capped TEA2025 amplifiers

First of all, the datasheet for tea2025b stated, that NP caps should be used only on input (allowing source to be referenced to ground). So there you need 0.22uF NP cap.

I noticed that the cap that changes everyting is the small serial capacitors that goes from ground into PIN 2 (OUT-1), 0.15 uF.

If I used ceramic or polyester capacitor, the chip started to draw 4 AMPS of current (max should be 1.5), and the distortion was huge.

It only worked when I used small...
