Thank you for your appraisal!
I have run this (LM675) amp with a DC gain of 10 with no lag compensation (about the lowest gain I think this thing can stand) and still see obvious distortion:
Here is our (supply shorted) OPA548 waveform with the…
Part Number: LM675
What would cause noise shown in the image below to appear on a non-inverting amplifier circuit. This only happens when I connect a small load that draws a lot of power (loads less than 100 ohm)? When the circuit is not loaded, the…
Part Number: LM675 Other Parts Discussed in Thread: OPA548 Hi,
I have a non-inverting op amp circuit shown in the image below:
The circuit works very well when connected to a high R load. However, when connected to a lower R load, the output oscillates…
Part Number: LM675 Other Parts Discussed in Thread: LM1875 Hi, I have the circuit below. 1 inverting amp and 1 non inverting:
The circuit works fine when no load (or large R loads) are connected. However, when I connect a 16 ohm high power resistor the…

I have the circuit below, a wien bridge oscillator that generated a 15V 700 Hz signal - the oscillator works well on its own when not connected to any load.
When I load the amplifier with…
When the LM675 is putting out 6.3 Vrms into a 1 ohm resistor we need almost 40 Watts across that resistor which overheats both the 5W resistor and the LM675 supplying its voltage.
For noninverting UA741 Op Amp

Part Number: LM675 Hi.
1.- Can LM675 work with single supply?
2.- Which is the minimum supply voltage for single supply? (Can it work with a single supply of +15V?)
3.- I have a LM675 supplied with a dual supply of +/-15. And the LM675 is quite hot even…
