• LT1167 LTSPICE noise simulation

    Hello everyone:

    I am using LTSPICE for the amplification of a voltage signal from the Wheatstone bridge. My sensor has not yet reached so I am currently doing the noise analysis in LTSPICE for LT1167. My purpose is to verify my noise voltage density…

  • LT1167 in LTSpice

    Hi

    I tried to build EMG sensor based on LT1167. I found typical application (figure 8) and try simulate it in LTSPICE.

    AC Analysis looks ok but something weird happen in trans.

    After first filter (Highpass - red wave) it looks ok but after second filter…

  • Indirect feedback noise simulation with LT1167 and AD8672

    Hello friends,

    I wish to do a noise simulation on a current source controller using the LT1167 instrumentation amplifier and the AD8672 low noise op-amp. what is the correct approach for noise simulation on a indirect feedback circuit like this? In LTspice…

  • LT1167 as High-Speed Current Monitor

    I am trying to use the LT1167 instrumentation amplifier as a low-side current monitor for a high-speed application and experiencing unusual behavior.

    Description of Application: I am measuring the voltage across a 10Ohm resistor to determine current…

  • Problem about OP amp LT1167 AIN8

    Hello, I am a student of Hongik univ, rep of Korea.

     

    I make an inquiry about OP amp, LT 1167.

     

    There were some products that broke out due to a large amount of heat generation during use.

     

    It is not possible to distinguish which products can function…

  • RE: AD8224 Low Frequency Noise Issue

    Hugagogo,

    Random comments:

      For the level of precision you are trying to achieve, I wouldn't even consider a two layer board.

    Four minimum.  I would also not use a dual.  Interaction, cross talk, layout problems, etc.

    For figure 10, they probably had…

  • Can AD8221BR, AD8622 improve current design?

    We are redesigning a test board due to heating in a few LT1167 (LT1167ACS8) and LT1352 (LT1352CS8) devices. Due to lack of information on the specific devices that heat up, done LT Spice simulation for circuits, and have nearly narrowed down on the problem…

  • RE: Oscillation and heating on AD8512 used as Sallen Key low pass filter (Gain=1)

    Hi Harry,

    Thank you for the reply.

    Active filter wizard was not used in design stage. The specification that we had to meet was a LP filter with fc = 100Hz. It was a redesign being done to solve heating on the earlier LT1352 (Opamps) and LT1167 (IA…
