DonвЂ™t Be Fooled by Voltage Reference Long-Term Drift
and Hysteresis вЂ“ Design Note 229
John Wright Lies About Long-Term Drift
Some manufacturers are now touting phenomenal
long-term drift speciп¬Ѓcations, 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 вЋ› 1 1 вЋћ
вЋњ вЂ“ вЋџ
K вЋќ T1 T2вЋ where: E A = Activation Energy (Assume 0.7)
K = BoltzmannвЂ™s Constant
T2 = Test Condition in В°Kelvin
T1 = Use Condition Temperature in В°Kelvin Equation the acceleration factor is 767 and the projected
вЂњbogusвЂќ long-term drift is 0.156ppm/1000hr at 30В°C.
For a 2.5V reference, this corresponds to a 0.39ОјV shift
after 1000 hours. This is pretty hard to determine (read
impossible) if the peak-to-peak output noise is larger …

LвЂ‰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 вЂњrealвЂќ 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 thatвЂ”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 possibleвЂ”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.
This article shows how to easily build …
