  • THS3491: IC blows up when powered.

    Part Number: THS3491 Other Parts Discussed in Thread: TL081 , LM4040 Hello. I'm having trouble with the THS3491 IDHAR, since it blows up when powered. I already bricked two of them. I bought them from Digikey (296-51646-1-ND). The board works, so it…

  • RE: TLE2426: Output voltage

    Resolved
    Hi Amir, the TL081 cannot run with a 3.3V single supply voltage. What sensor do you have? Can you tell a bit more about your application? Kai

  • OPA1641: OPA1641 SPICE model question

    Resolved
    Part Number: OPA1641 Other Parts Discussed in Thread: TL081 , TL072 , TL082 , Hello, I'm modeling the input impedance of a simple non-inverting stage and finding that the impedance is very different from other TI JFET input opamps. Here is the simulation…

  • RC4559: Replacement for 4739 dual op amp (audio)

    Resolved
    Part Number: RC4559 Other Parts Discussed in Thread: RC4580 , TL081 , TL071 Hello, I'm searching a replacement for the 4739 dual op amp (vintage guitar effect). I think the RC4559 should be a good candidate, it's pretty similar. The pin-out is different…

  • RE: TL3016: Input noise in this and similar analog comparators

    Resolved
    Hi again Kai The comparator inputs are at low mpedance; the non-inverting input is driven by an op-amp, actually an NE5534A, and NOT a TL081 as shown. Under quiescent conditions the signal here is a +/- 2V peak triangle.The inverting comparator input…

  • RE: TL084: OP amp output distortion even at low frequencies

    Hi Yu, Got to love the TL081 and still have a few from the 80's hanging around in the parts drawers. You also might check out FSK (frequency shift keying) modem pair via phase lock loops order to reduce the IR bandwidth requirement. The principal…

  • RE: TINA/Spice/LM317: LM317

    Hi Tang, Can you provide the .TSC as Manoj requested? .TSC file is the schematic file (not the model netlist file nor .TSM file). This is the file when you click and open it will show the snapshot schematic picture that you post on your very first post…

  • RE: TINA/Spice/LM324: LM324

    thank your reply. I change lm324 to tl081. it is working without kik off voltage @ t=0. but i face another issue when design sine generator & simulate both at same time , sine is not coming). when simulate separately it is working. how rectify this…
