LM4562 DATASHEET PDF

Amplifier output power may be scaled LM Filterless, 2. Ideal for automotive, industrial, and general lighting applications, they contain a high-side LM The LM is a switching regulator designed for the high efficiency requirements of applications with stand-by modes. It can provide simple down conversion to output voltages as low as 0. BQ : Power. Power Minder tm ic.

An op amp is part of a larger circuit and is chosen because its specs match those required for the circuit. The sound quality comes from the entire circuit, not the op amp. Switching op amps is likely to cause as much harm as good. Then they went out a suggested that their op amp could be used as a direct replacement for almost any other op amp on the market, despite having different voltage specs!

The level of irresponsibility here is repugnant, and the reasons for failure seen in my post have displayed themselves rampantly in the wild. The job of the amplifier should be to provide clean gain. Those changes will be controllable, and immediate. No opening up your amp, waiting 10 minutes for the caps to discharge, going in with pliers, and then losing all audio memory of what it sounded like before. With EQ, you can hear it immediately and tune to get exactly what you want.

When you alter the sound signature with an op amp, more than likely you are just making the amplifier perform non-linearly. I look back and wonder what I was thinking to mess with precisely measured perfection.

I could only make it deviate from that perfection. All I did when I tried rolling op amps was mess up good engineering. Yet, I hear this so often, that I must take exception on your assertion that: " Whoever it was, perhaps it was simply an age-old theory that went viral 40 years ago, some "scientific" BS that perpetuates itself endlessly when discussing sound quality observations.

The sound so compelling, rich, real, it draws us closer. This notion of "Oh, I forgot what it sounded like how I felt a moment ago" is pure Bunk. To think that sound is a complete, well-understood "science" as it relates to human interpretation is both untrue, and unwise.

An open, educated yet humble mind, however, is a prerequisite. Not at all. Albert Einstein was one such chap, early last century.
