Part Number: LM324 For all of these opamps, on the datasheets I see "Output Current" and a value is given for Min and Typ (but not Max). (Page 6 of the LM324/LM324A/LM324K/etc. datasheet, for example)
Am I to assume these really require a minimum…
Peter,
Vio of LM324 can be as high as +/-7mV although that is rare. U3D has a DC gain of 101 so output could possibly vary by 14mV * 101 = 1.4 V. Therefore Vio could be the reason for output difference of 0.55V. I am also concerned about C14. That…
Hirokazu, Just like the LM324 and LM324K (and LM324A and LM324KA) share the same EC table data. LM2902 and LM2902K will also share the same EC table data. I will add this to next LM2902 data sheet update.
Umesh,
The LM324A and LM324AD are the same. The "D" means SOIC package.
The quality of the models are not the same. Where did you get the LM324 models?

We are using AD5372BSTZ DAC chip for our ECU test system. If we connect buffer(LM324A) in single supply mode DAC output voltage is intact. As we are facing…
Eliezer,
Input common mode at ground is fine. Usage with or without with the feedback capacitor is also fine. I even tried to raise GND to +200mV thus making the noninverting inputs 200mV below GND and the LM324 worked well (for VOUT >200mV because output…
Vladimir,
Going back to your original question. LM324A meets your requirements when output current flows to ground. How fast does the comparator need to be?

I have a National Semi LM324AM in production design as 5.0 voltage reference, but TI LM324A output oscillates 360mV when used to replace National Semi part.
