AN7060 Unobtanium issues... Want to find similar to drive Darlington Power ICs

[SVI2004A]

I am trying to find a chip that functions similar to AN7060 or AN7062... Used to drive output stage easily -see pic... ( stuff in dotted line is in power IC)

Have seen ICs in late model amps that do a similar thing, though I can't think of their part numbers

Regards Baily 🙂

The LME49810?

 

[SVI2004A]

Cool... I will look into that one 🙂

LM4702 is a dual driver, LME49811, LME49810 mono driver with Baker Clamp, LME49830 for MOSFETs. Linear Tech LT1166.

Yep, quite bit about the LME49811 and National's other parts on this forum. They're often overkill, though---driving the bias string with a typical op amp on +-15V rails provides sufficient swing for about 88% of listeners.

I have a pair of original AN7060. They are in a working amplifier pcb i removed from a junked out phillips stereo system. As it goes the amplifier dosnt sound too bad at all.

[SVI2004A]

The output ICs I will be driving are SVI2003A SVI2004A and STK2058IV

Resistor values mostly were denoted on the SMD resistors... The 820 ohm one is a thermistor.
These are stereo power amplifier ICs... Pins in ( ) are 2nd channel

I am thinking of running with the LM4702.

I am curious about source and sinking aspect... As voltages in pins 1(16) and 5(12) at idle are +/-1.8v.

I reckon it should work. But would like to hear from those that have used these before or know of anything I overlooked.

Cheers 🙂
