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…
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…

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…

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…
Part Number: LM675 Hello Team,
Can you tell me the Thermal Resistance (θJA, θJC, θJP) of LM675?
I would like to compare with other products.
Regards,
Masakazu
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.

Part Number: TL071A Other Parts Discussed in Thread: TL072B , INA121 , TL072A , TLC2202 , LM675 , Hi,
Our customer is considering using TI's OPAMP under vacuum about 10^-4Pa. Is it okay to use it? Is this kind of test conducted in reliability testing? (As…
