    Don’t Be Fooled by Voltage Reference Long-Term Drift
    and Hysteresis – Design Note 229
    John Wright Lies About Long-Term Drift
    Some manufacturers are now touting phenomenal
    long-term drift specifications, based on accelerated
    high temperature testing. THIS IS A DELIBERATE
    LIE! Long-term drift cannot be extrapolated from
    accelerated high temperature testing. The only way
    long-term drift can be determined is to measure it over
    the time interval of interest. The erroneous technique
    produces numbers that are wildly optimistic and uses
    the Arrhenius Equation to derive an acceleration factor
    from elevated temperature readings. The equation is:
    AF = e EA ⎛ 1 1 ⎞
    ⎜ – ⎟
    K ⎝ T1 T2⎠ where: E A = Activation Energy (Assume 0.7)
    K = Boltzmann’s Constant
    T2 = Test Condition in °Kelvin
    T1 = Use Condition Temperature in °Kelvin Equation the acceleration factor is 767 and the projected
    “bogus” long-term drift is 0.156ppm/1000hr at 30°C.
    For a 2.5V reference, this corresponds to a 0.39μV shift
    after 1000 hours. This is pretty hard to determine (read
    impossible) if the peak-to-peak output noise is larger ...

    How to Choose a Voltage Reference

    L DESIGN FEATURES How to Choose a Voltage Reference
    by Brendan Whelan Why Voltage References? 5V It is an analog world. All electronic
    devices must in some way interact with
    the “real” world, whether they are in
    an automobile, microwave oven or cell
    phone. To do that, electronics must be
    able to map real world measurements
    (speed, pressure, length, temperature)
    to a measurable quantity in the electronics world (voltage). Of course, to
    measure voltage, you need a standard
    to measure against. That standard is
    a voltage reference. The question for
    any system designer is not whether he
    needs a voltage reference, but rather,
    which one?
    A voltage reference is simply that—a
    circuit or circuit element that provides
    a known potential for as long as the circuit requires it. This may be minutes,
    hours or years. If a product requires
    information about the world, such VIN 18k LTC1286

    Wireless Precision Temperature Sensor Powers Itself,
    Forms Own Network, Enabling Easy Deployment
    in Industrial Environments
    Kris Lokere While the Internet connects people via a worldwide computer network, the Internet of
    Things (IoT) refers to a growing trend to create relatively simple devices that interconnect
    and share data independent of computer or human intervention. The IoT has the potential
    to increase efficiency, improve safety and enable entirely new business models in just about
    any facet of life or industry. For example, to reliably and efficiently operate an industrial plant,
    it helps to have as many monitoring (or control) points as possible—more sensors means
    better monitoring. The device-to-device networking of the IoT simplifies distribution and
    networking, making it easy to expand the number and reach of sensors throughout a plant.
    Exponential increases in the number of
    sensors can be achieved by eliminating
    all cabling requirements through the use
    of robust, wireless, micropower sensors
    that run for years on a small battery.
    Better yet, eliminate the need to replace
    or recharge batteries. Instead, sensors
    harvest energy from their immediate
    environment, taking advantage of locally
    available energy sources, such as light,
    vibration or temperature gradients.
