  • LM258A: LM358A Vcm question!

    TI Thinks Resolved
    Part Number: LM258A The usage of the customer is the follower. The power supply for LM258A is VCC=20V, VGND = GND, PVin+= 18.2v.The customer's question is, if Vin+ is applied with a voltage of 18.2v in the full temperature range, will there be any problem…

  • LM258A: negative input voltage

    Resolved
    Part Number: LM258A I use the LM258A and Vcc is +-12Vdc. From the data sheet, the maxmum negative voltage is -0.3Vdc. I want to confirm that the maxmum negative input voltage is -0.3vdc or -12.3Vdc(-12v-0.3v)? Thank you. Best Regards Jiunhung

  • RE: LM258: LM258 Input Common Mode Range issues

    Resolved
    Hi Ron, I checked LM258A, Ibmax is only 100nA, much lower than 300nA. It is much better to replace. I simulated by 100k resistor, the minus voltage of IN+ Pin is lowered to -0.445V assumed the input voltage is -0.5V. For LM258A, dV=100nA*10M=1V, allowed…

  • RE: LM258: LM258DRG4 & LM258DR performance is diff

    Alex, That information can be found here. http://www.ti.com/product/LM258/pinout-quality The only potential difference listed is lead finish. The drift observed is not caused by the part number difference. Is the drift a change 'over temperature' or change…

  • RE: LM3886: Thermal Resistance

    Hi Nagata, Are you referring to the thermal resistance of silicon - top side plastic package? If yes, this parameter is not measured, because this device is not designed to dissipate power through plastic top side and we can obviously know this parameter…
