• LT5400　Derating Curve

    Hi, 

    My customers are considering using the LT 5400.

    Is there data on the Derating Curve( Ta ) of the LT 5400?

    Or is there a graph of Power Dissipation vs Thermal Resistance Curve?

    Best regards,

    Yuya

  • LT5400 - Matching Ratio Temperature Drift - stability, different parameters

    In our design we require the Temperature Coefficient of the Resistor's Matching Ratio will be max 0.2ppm/°C ( "0.2ppm/°C Matching Temperature Drift" as per datasheet). That is the most important parameter in the design.

    I can see…

  • RE: ADA4817 differential probe

    Hello,

    Yes it is quite hard to find a discrete diff amp with wideband as 200MHz.

    You can opt to use ADA4817 but I suggest, you have to use matched resistors network rather than discrete one.
    You can check LT5400 for quad matched resistor network.

    The LT5400…

    1. 这三款ADC的性能都不错，输出速率都能高于1kHz

    2. 推荐您使用LT5400配合ADA4177使用

  • LTC6363 single-ended to differential

    We try to use LTC6363 to convert the input single-ended signal into a differential signal. The Gain factor was calculated to be 1, but the actual measured gain factor was 0.7. The resistor we used is LT5400-5, an 1MΩ resister pack. Could you help me solve…

  • RE: LT1997-2 Distortion Specs

    In my application LT1997-2 internal OPAMP will operate inside [V– ; V+ – 1.75V] so it won't transition into OTT mode. The LT5400 solution will provide worse CMRR inside 0-1kHz range. I don't have oppurtiny to do the THD benchmarking on LT1997-2 eval,…

  • RE: Gain resistor: will metal foil significantly reduce noise?

    To add to the conversation, metal foil resistors are useful for temperature stability, since they have low temp coefficients. If your circuit is intended for absolute accuracy over temp, then use metal foil. If you need good matching over temp, I would…

  • RE: Instrumentation Amplifier Gain resistor(s)

    DB,

      You will find that the majority of error, especially over temperature, usually comes from the resistors.

    You can go to Digikey.com and buy 5%, 2%, 1%, 0.1% resistors, etc. with tempcos of 50 ppm, 25 ppm, etc.

    but the best thing is to use a monolithic…

  • 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.…

  • circuit for ultra precision INA @gain = 1.0

    I want an output signal which is the difference of Vexcit+ to Vexcit- (up to +/-5V each) to be ground referenced with high accuracy.
    Normally this is the job of an INA. But at gain 1 the output offset voltage of AD8421 is dominant.
    In my actual test circuit…
