LM3886: LM3886's thermal distortion question..

Part Number: LM3886


Tool/software:

Hi everyone,
My question will be about the thermal distortion of LM3886.
As it is known, discrete amplifiers are generally preferred in audiophile use due to thermal distortion concerns. In order to clarify this phenomenon, which is probably an urban legend;
Although the open internal circuit of LM3886 has not been published, as far as I understand from the simplified schematic, this amplifier consists of a design that is almost impossible to realize discretely, with input stage and voltage amplifier/phase splitter stages fed by many-stage CCSs.
Therefore, can we talk about the effect of thermal distortion that will occur in various stages due to the heating of the output stage and therefore the heating of the whole wafer on the general sound quality? Have there been any studies on this subject?
Thanks in advance for the answers.

  • Hi Ozgur,

    Usually, the spec provided in data sheet is applicable through the operating temperature range, until it reaches the overtemperature limit which either disables the device or reduces its performance to keep it safe.
    I don't have a performance comparison of IC vs discrete amplifiers, unfortunately.
