Article Request: Composite Amplifiers

Postby Ravindra » Sun Sep 28, 2014 11:46 am

Hello Elektor Audio Team,

Unless I have missed it, there is very little that has appeared on 'Composite Amplifiers.'

With some very special audio specific performance op-amps in the market, a guide on how one could use it to improve the performance of some of the popular chip-amps like LM3886 or the TDA7293 would be wonderful.

There is a small article in the Elektor 303 Circuits titled 'Tuning AF Power Stages.' I have gone through it. I think the polarity of the op-amp in fig. 1 (inverting config) is reversed. This article can be taken forward with some concrete examples.

Thanking you all in advance and regards,

Ravindra.
