LM4041

Other Parts Discussed in Thread: TL431

Is the LM4041BIDBZR usable as an op-amp similar to the traditional TK431?  If so, what is the small signal Vka/VFB gain vs frequency?   Are there curves/charts available?


Thank you!

    Winston,

    Yes it can be used as an amplifier except the common ("ground") pin is the cathode. For the TL431 the common pin is the anode. Therefore the LM4041 is easiest to use in a negative voltage/current amplifier setup (grounded cathode). 

    I do not have a bode plot for LM4041, but I do have a curve for the TL4051 (similar device to LM4041).
    Green is gain (dB) and blue is phase (degrees)
