Hi Experts,
Our customer is trying to simulate the following LM311 circuit with hysteresis in LTspice:
The circuit is supposed to be a comparator with hysteresis centered around 2.5V, with high threshold 3.1V and low threshold 1.9V.
VIN is at a constant 2.5V when the simulation runs, but the output oscillates. What could be the cause of this problem?
Please help.
Thank you and best regards,
Gerald
