• LT1991

    We are exploring the opportunity to use LT 1991 for below requirement:

    1. Design 1 - Single ended input to Differential output; Gain of 1,2 – Vin (Single ended) ±18V
    2. Design 2 - Differential input to Single ended output; Gain of 0,6 - Vin Range…
  • Application of LT1991

    I would like to use LT1991 as a differential amplifier with Gain of 0.4

    My supply voltages are +12VDC and -12VDC

    Input = differential voltage signal of 42V max.  (i.e.,  +21V to -21V w.r.t. GND or 0 to 42V w.r.t. GND or -42V to 0V w.r.t. GND)

    I am trying…

  • LT spice simulation for LT1991

    This is with reference to LT1991 configuration discussed in datasheet on page no. 24, figure 17, VCM = –56V TO 53.2V . 

    I tried simulation with same configuration with different input combinations. Please note, this configuration is having gain =1…

  • RE: Differential Amplifier with higher gain bandwidth??

    Hello Shurp,

    How are you?

    You may want to check out LT1991 - it uses 450kohms resistance with 560kHz BW (G=1).

    There is a tool for it if you want to explore and simulate in LT Spice - LT1991 Beta Tool

    I hope it helps.

    That's all,
    Sham

  • RE: Using differential Amplifier on LTC1968, and the input voltage changes; please help

     Per your recommendation, I used LT1991, and I increased the gain until the input was not affected. Below is the diagram I chose to use; the diagram below is on Page 19 of the datasheet. The issue I currently have is that the output is not stable…

  • LT1991AIMS#TRPBF and LT1991IMS#TRPBF Difference

    Hi,

    Please help to advise the different between LT1991AIMS#TRPBF & LT1991IMS#TRPBF?

  • RE: Using the LT6015 to monitor a stack of four 3.2V 100Ah LiFePO4 cells?

    Hi,

    It seems to be workable. If you need well matched resistors, you may use LT5400-2 which can give you up to 0.01% matching. You could also add some capacitors for filtering in parallel with the feedback resistors R2 and R6 and R4 and R8 to ground.…
