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 …

DESIGN FEATURESвЂ‰L Reliable Precision Voltage Reference
with 5ppm/В°C Drift is Factory Trimmed
and Tested at вЂ“40В°C, 25В°C and 125В°C
by Michael B. Anderson and Brendan Whelan The LTC6652 reference is a precision
low drift voltage reference that includes
advanced curvature compensation
circuitry and post-package trim. To
guarantee reliable performance, these
parts are tested at вЂ“40В°C, 25В°C and
125В°C to verify they meet specification
across the entire temperature range.
This comprehensive testing ensures
that the LTC6652 can be used with
confidence in demanding applications. One result of this testing is
demonstrated in Figure 1. The output
voltage versus temperature for several
randomly chosen parts shows a drift
characteristic that is consistent from
part to part. This is a result of a propriLinear Technology Magazine January 2009 Compare the Real Specs:
Is the Temperature Range
Operating or Functional? When comparing voltage references for
use in demanding environments, it is
important to know, with confidence, …

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
