Risk Assessment Advice for High Reliability Amplifiers
Tim Regan and James Mahoney Introduction
In long life, high reliability systems, supplied power is
provided only to essential circuitry. As a result many of
the unpowered circuits may have voltages applied to inputs and outputs without proper supply biasing. As part
of any diligent system safety risk assessment, a question
often arises; will the unpowered components be damaged,
degraded, or impair circuit performance under these
abnormal operating conditions?
The purpose of this article is to provide advice for what
lies within the pins of several common amplifiers used in
these applications. Most of the amplifiers of interest are the
radiation hard amplifiers so indicated with a device prefix
of RH. Another amplifier, the LT6016, is particularly robust
with over, under and reversed polarity voltage conditions
and is included for reference.
With no power applied to the amplifier, forcing a voltage
between two pins will cause a current to flow. The magnitude of this current differs from pin to pin and device to
device. A curve tracer is used to show the current vs voltage
characteristic when overdriving specific pin combinations.
Referencing these curve trace plots will provide an indication of the magnitude of current flow for a particular …

DESIGN IDEAS Designing the LT1167
by Adolfo A. Garcia
Instrumentation Amplifier
into a Single 5V Supply Application
Introduction Circuit Operation
operate near the sensor or circuitвЂ™s
positive supply voltage or ground
(common). Even though the signal
conditioning circuitry need not operate at the extremes of the supply
voltage range, the output voltage swing
of the circuit should be as large as
possible for maximum dynamic range.
The circuit illustrated in Figure 1
achieves high precision performance
while operating from a single 5V
supply. The trick here is to reference
the dual-supply instrumentation
amplifierвЂ™s inputs to a stable midpoint supply and then follow the
instrumentation amplifier with a
single-supply precision operational
amplifier with a rail-to-rail output
stage. This вЂњcompositeвЂќ instrumentation amplifier uses an LT1167 (a high
performance instrumentation amplifier in an SO-8 package) for the input …
