Op amps always operate with some amount of external feedback where some of the output signal is fed back into the input. If we start looking at op amp circuits, we can see how this is being done with feedback resistor RF. To the right is your typical inverting op amp circuit, the gain of which is determined by Rf / Ri.

An operational amplifier can amplify signals having a frequency ranging from 0 Hz to 1 MHz This means that OP-AMP can be used to amplify DC signals (0 Hz) as well as AC input signals (high-frequency signals). Furthermore, it is designed in such a way that external components like resistors, capacitors, etc. can be connected to its terminals. And by adding …

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 36V. Thread Starter zero_coke Joined Apr 22, 2009 294 Dec 3, 2011 #3
