  • LM675: Weird behavior at certain input voltages

    Resolved
    Part Number: LM675 Other Parts Discussed in Thread: OPA548 , LM3886 I am trying to drive a proportioning valve with this op amp. For this purpose, I have designed a non-inverting op amp circuit to amplify a 0-5 VDC value to 0-30 VDC value with an output…

  • LM675: Crossover distortion with loads below 100 Ohms

    Resolved
    Part Number: LM675 Other Parts Discussed in Thread: OPA548 , LM1875 Playing with the output snubber, I was able to remove most of the distortion in this circuit with loads below 100 Ohms (no distortion is visible with larger loads). I removed the current…

  • 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…

  • 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 …
