The most important effect of this is to make the overall amplifier gain almost immune to changes in the amplifierunit gain, and dependent almost entirely on the feedback network components.
The temperature information acquisition unit based on C8051F330 is composed of processor, analog front-end operational amplifier, serial port communications and so on.

While it had excellent sound quality, the low efficiency of the power amplifierunit made commercialization difficult.
