Hey Cedrick,
Thanks for asking about the LM124. Please see the following thread for the differences between the different versions of the LM124

Hi Philip,
exactly! See the differencies in the "absolute maximum ratings" referring to negative input voltages in the datasheets of LM124A and LM124-N, e.g., ...

Hi Js,
the LM124 and LM124-N are different chips. The LM124-N is the original from National Semiconductors and the LM124 is a clone from TI. And different chips have different specifications...

Hi Hao,
you wrote:
"On the other hand,If the output resistance is set to 2k resistor, the amplifier circuit works properly."
Yes, in this case the 2k resistor can absorb a big portion of the load current.
Yes, the LM124 is unity gain stable…
Hi Ray,
The LM124A is an industry standard product and all LM124A products will have the same specifications.
The differential input voltage range between the two inputs is 32V. This means that they meet +32V or +/-32V.
For both parts, the input offset…
Jason,
There is a good schematic on page 10 of the data sheet. However the parasitic diode from the resistor on output pin to VCC is not obvious. The resistor is P doped (think of an anode) and it lives in an N doped area (think of a cathode). The N doping…
Hello Dimitris,
The quiescent current is typically 1.4mA for ALL four amplifiers combined (or 350uA per amplifier).
One ohm is much too large of a load. it will never be able to drive that.
The sinking and sourcing capability is shown in the Output…
Kamlesh,
RE: Can switch on of +15V alone with -15 line open circuit or vice verse stress the op-amp? If the input pins or output pins become negative voltage relative to LM124 GND pin then input current can flow. If this current is limited to 10mA or less…
