Hi Circuit Gurus,
I would like to ask your inputs and recommendations to improve this amplifier circuit driving a 4 ohms motor(Op amp_Quasi-complementary.jpg). A DAC circuit outputs a 0 to +/-10V stepped sinusoidal wave and goes to the inverting input of the op amp. A quasi-complementary provides the current drive to the motor. A +/-10V corresponds to a +/-1.5A load current.
I've searched for more information regarding quasi-complementary amplifiers and found an improved quasi-complementary amplifier. Very, very similar but the upper and lower pairs are reversed. I have spare transistors so it would be nice to use the ones I already have in improving this amplifier.
I hope adapting the improved circuit to the existing amplifier is as easy as plug and play.
Would really appreciate your inputs and recommendations.
Thanks in advance guys. Nuki
