The LM386 is another common op-amp IC that finds its home in audio applications. It can safely drive loads from 4 to 32 Ohms with kHz frequencies with reasonable gain and low noise. Although the above components are common and low-cost, these components are not often used in production-grade products, especially for advanced …

Another common op-amp circuit is the inverting amplifier ( Figure 4 ). As the name implies, the output voltage is amplified with opposite polarity as the input. Figure 4 The inverting amplifier produces the negative value of the input, scaled by the ratio of the two resistors.

The OPA627 can be accurate to a fault, if your recording has unpleasant detail in it that another op-amp would ignore or deemphasize. If you have flawed recordings, you may prefer the pleasant lie told by the AD843. Bottom Line: This is a serious contender with the Burr-Brown OPA627 for the title of "best op-amp I've ever heard". I view these two chips as rough equals; …

With a 30V supply and a single-ended amplifier circuit the power into 4 ohms is only 13.8W. Maybe your speakers are rated at 60W peak which is 30W RMS. An OPA134 single, OPA2134 dual or OPA4134 quad opamp is excellent. The max allowed supply is …
