TPA3136D2: Reference Design Schematic for Altium Designer

Part Number: TPA3136D2

Hello,

Is it possible to get the reference design for this part as a ECAD schematic file? Specifially for Altium Designer? We've been using this design in one of our products and it has caused some issues with popping noise. I would like to minimize issues in our new prototype by using a complete reference design to work from. Do you provide this service?

Best regards,

    Hi Emir,
    I suppose the pop noise occurs during the device power-up. The main cause is the imblance between the differential input. Are you using single-ended input mode or differential input mode? Usually it's much easier to cause pop noise issue in the single-ended input mode, so please use differential input mode as much as possible in your design. Please use 1uF or less value caps for input DC blocking capaciotors. If you have to use single-ended input mode, please make sure there is no complex circuit between DAC/Codec output and AMP INP, just one 1uF capacitor is good. We can help to review your previous SCH design if it's available. Please refer to our TPA3136D2 EVM design, which is a good example: www.ti.com/.../slou444a.pdf
    Best regards,
