I like to built a HI HI -END , a univesal , true/pure class A opamp base on N.PASS circuit to replace my current opamp in my cd player . I need somebody to help me on this . My dac is SM5872 .
What type of mosfet/JFet should i choose ? Wide feq ,high current
high power low s/r .......s/n ...... ? and i know the voltage from DAC is very low ~ 0.3V i guess. How to mod this circuit to work and output around 2~2.5V ? OR resistor network that i can direct drive my power amp ? thank you ! *** If anyone know the PASS D1 DAC opamp circuit diagram please let me know !****thank a lot !
