  • RE: LM675: Crossover distortion with loads below 100 Ohms

    Resolved
    Hi Kal, 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…

  • LM675: Noise on output when load is connected

    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…

  • LM675: OP AMP oscillates briefly then oscillation die out and outputs DC component only

    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…

  • LM675: Distortion/noise only when load is connected.

    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…

  • LM675: Inverting amplifier not amplifying AC component of input

    Resolved
    Part Number: LM675 Other Parts Discussed in Thread: TLE2072 , Hi, 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…

  • RE: LM675: Case Number: CS0720693

    Resolved
    Thomas, 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 P RMS P RMS P RMS …

  • LM675: Single Supply?

    TI Thinks Resolved
    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…
