  • LMH6628: Input stage of LMH6628

    TI Thinks Resolved
    Part Number: LMH6628 Tool/software: I have a quick look at the datasheet of LMH6628. I am wondering how do we know that this is BJT input Operational Amplifier. I have searched the datasheet with "BJT" and found no result. I have not deeply looked in…

  • LMH6628: Outgassing test

    Answer Suggested
    Part Number: LMH6628 Tool/software: Hi, Does LMH6628 have outgassing test? If customer has test by themselves, is there any concern about the test? Thanks.

  • LMH6628: TINA TI Pspice Noise Model

    TI Thinks Resolved
    Part Number: LMH6628 Other Parts Discussed in Thread: TINA-TI Hello, We need to know if the LMH6628 PSPICE SNOM132 has Noise Model within the Macro file. If it doesnt, how can we edit it with its datasheet specs? Thank you for your support! LMH6628…

  • LMH6628: Unexpected behavior observed with LMH6628

    Part Number: LMH6628 A customer has encountered unexpected behavior with the LMH6628 in their product and are in initial investigation stages. One thought is what might happen to the LMH6628 op amp if the input common mode voltage range is exceeded…

  • LMH6628QML-SP: LMH6628QML-SP vs LMH6628 supply current

    TI Thinks Resolved
    Part Number: LMH6628QML-SP Other Parts Discussed in Thread: LMH6628 , , LMH6628QML Hi Team, Need your help in confirming this. The LMH6628 datasheet states that its supply current is max at 12.5mA "per channel". While for the LMH6628QML-SP, datasheet…

  • RE: LMH6628: Termination of unused pins

    Resolved
    Hi Thomas, That is correct. You can connect every NC pin to ground. Best Regards, Robert

  • LMH6628 characterization question

    Other Parts Discussed in Thread: LMH6628 , LMH6628QML Our question is regarding the LMH6628 amplifier. We would like to know the amplifier's ability to reach its high and low voltage rails when driving impedances greater than the 150ohms (shown in figure…

  • RE: Delay circuit using Ti IC LMH6628

    Hello, I think you need to use dual supplies (Vs= +/-4.5V) in order to not violate the input CM voltage range. For the LMH6628, the input CM range (CMIR) is 1.3V above V-, and 1.3V below V+ (or +/-3.7V when operated from Vs= +/-5V). Alternative is to…

  • RE: TINA/Spice/LMH6628: To unity gain or not to unity gain

    Britt, I have used the model form the spice macros -> op amp and then selected the LMH6628. This is the same right? I would still like recommendation for unity gain vs 3-4X gain + signal attenuation. Best regards, Marko

  • LMH6628 TINA SPICE model defect, uses node 0 internally which creates large current spikes

    Other Parts Discussed in Thread: LMH6628 Dear TI: Please fix the LMH6628 TINA SPICE model. Since the model runs from V+ and V- only (there is no ground pin) there should not be any node 0 (ground) connections in the model. Look inside the macro…
