    1. AD8512ARZ EIPD Issue

      Hi, I am having a problem about AD8512ARZ opamp. The product I use in serial production sometimes burns from the pins of 1,6 and 7. The application of this component is a basic non-inverting amplification with 20khz frequency. Due to product supplier explanation, the reason behind it is …

      Have you taken a scopeshot of the PWM_OUT node? It's driving a 9M cable? This by itself could represent a rather difficult capacitive load, and you're trying to drive it at 20kHz, which will draw (20kHz*24V*Cload) current from the op-amp's output (at least …

      Hi Emrah, Yes, I think that any information will be helpful. I don't really like the fact that the output stage works with saturation when the input signal is "high" and in an undefined state when the input signal is " low". This mode is valid for comparator but not …

      Hi Fdelaram, The PWM_In voltage is 3.3V. As you say with 7.8 gain, it can be a problem. I will consider on testing with reducing the gain within the range of VS-2V. Maybe because of this, the problem shows an EIPD. I will test again with …

      Hi Krill, Sorry for the late answer, I was in testing for this issue. So here are the are the answers for your question; Double opamp have two inputs and both inputs have same frequency and amplitude voltages (approx.3.3V) and both controls a series of fans(one output …

      Hi Emrah, As seen on your configuration, the 24V supply voltage is still within the range. You can actually raise it to 30V. The Abs Max is 36V, but it is not advisable to work on your Abs Max rating. I would like to ask the voltage level of your …

      Hi Emrah, Ok, I will try to help and make a mental analysis of your problem. Now I have else few questions: If you uses double op-amp, which function performs second op-amp in this package? This op-amp damages too? I can"t still understand, which type of …

      Hi Krill, Yes it might be possible by design but still not sure. Above, you can see a part of this non-inverting amplification. (4th and 8th pins should be reversed, my mistake, just accept the 4th pin as GND and 8th pin as source). General issue is coming …

      Hi, Would you show diagram of this amplifier? You said about 1 6 7 pins damaging. Pins 1 and 7 is outputs and damaging of outputs is possible only if at them apply voltage beyond supply rails, as far as I know. This scenario is possible in your design? Regards …

      Hi Krill, Thank you for your answer. I am still simulating the circuit part in order to find what might caused this EIPD damage. Do you have any idea about the major reasons for EIPD? (Wrong harness application, grounding, etc.)
