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

The LME49810?
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.
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
