The AMP on TDA7293 is a class AB power amplifier. One of the main features of this microcircuit is the use of field-effect transistors in the preliminary and output amplification stages.
The TDA7293 microcircuits, if implemented correctly, surpass in sound quality many amplifiers based on discrete elements popular in the recent past. The main plus is low cost, a small number of piping components, and a short path.
A wide range of supply voltages, an output stage on field-effect transistors, a low coefficient of nonlinear distortion makes it possible to build an amplifier with a power of 20 to 80 W, which makes it possible to classify an amplifier based on these IMCs as a Hi-Fi.
