The load does have a high TCR, and its resistance does increase but still stay within the ohm range. When driving nonlinear reactive loads such as motors or. I suspected this was related to my problem, but I wasn’t sure how to calculate gain for since it wasn’t an amplifier. Since the die temperature is directly dependent upon the. It has a tendency to oscillate although sometimes to works okay, just often enough to give me hope that I might be close.

The thermal requirements can become more difficult when. If a smaller heat sink is required for.

I’d appreciate any advice. F or so without. Its remote from the circuit and fed by about 2 ft of BNC cable, so there is a slight capacitance in parallel with it.

The above equation is. I’m trying to build a pulsed voltage controlled current source using an op-amp. The LM has a sophisticated thermal protection scheme.

C, the LM shuts. It is advisable to keep the output com.

Power Operational Amplifier

Wide common mode range. High performance power op amp. Oscillations in voltage controlled current source Ask Question. Input Common Mode Range. It starts operating again when the die temperature.

LM from Texas Instruments

Assumes T A equal to 70? This is a rather large heat sink and may not be practical in.

LM is connected directly to a capacitor with no series. The problem can be eliminated by placing a. Just try adding compensation network as Fig. C unless otherwise specified. When the load is resistive, the maxi.


The LM not only limits current to. C, but if the temperature again begins to. The standard protection for this. Swing vs Supply Voltage.
