  • RE: LM124A: LM124AJ

    Resolved
    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... Kai

  • RE: LM124A: Power supply sequencing and use as a voltage follower

    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., ... Kai

  • RE: LM124: Open loop gain frequency response request

    Hi Jason, have a look into the datasheet of LM124-N. Figure 5 shows such a graph. The LM124 should behave very similarly. Kai

  • RE: LM124: Vcm impact Vout issue

    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…

  • LM2902-N: Current sense amplifier output stuck

    Part Number: LM2902-N Other Parts Discussed in Thread: LM2902 , , LM324 Dear TI, In my application I need to measure a 12V, 0-500mA current from the positive lead (high-side measurement) so I tried the application circuit named "Current Monitor" shown…

  • RE: LM124 ESD Protection

    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…
