• 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…

  • 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: Input bias current return path for LT1167

    By the way, R6 (across your source V3) has no effect on the operation of this circuit and can be removed with no effect.The LT1167 In+ is driven by a source and does not need an additional DC bias path as drawn.

  • 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…

  • RE: Problem about OP amp LT1167 AIN8

    Hi TYun835

    How hot did they get?  If they stayed below 150 degrees, then the parts should be okay.

    You could check specs like offset voltage and gain error and bias current and supply current, but the problem is that those specs could be okay but then…

  • 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…
