Input Filter Prevents Instrumentation Amp RF Rectification Errors - 11/13/03
EDN-Design Ideas: Instrumentation amplifiers serve in a variety of
applications that need to extract a weak differential signal from large common-mode
noise or interference. However, designers often overlook the potential
problem….....(design idea added 1/05) |

Instrumentation Amp has Differential Outputs - 08/19/04 EDN-Design Ideas:
State-of-the-art ADCs accept differential inputs, allowing you to differentially
implement the entire signal path from sensor to converter. This structure provides
significant performance advantages, because differential signals increase the
dynamic range, reduce hum, and eliminate ground noise. Figures 1a and 1b show two
common.....(design idea added 12/04) |

Instrumentation amp has low offset drift and low frequency noise - 08/21/08
EDN-Design Ideas: By cascading instrumentation amplifiers, you can achieve an
instrumentation amplifier with decade-gain having low offset, drift and LF
noise.....(design idea added 008/09) |

Instrumentation Amp Makes Noninverting Integrator - 09/19/02 EDN-Design Ideas:
Figure 1a shows the classic implementation of an integrator. The circuit has two
properties that may be undesirable in same applications: It necessarily inverts, and
it requires a split-supply or midsupply reference. Figure 1b shows an implementation
of an integrator that uses an LT1789 instrumentation amplifier.....(design idea
added 12/04) |

Instrumentation Amp Provides Unipolar and Bipolar Outputs #2 - 08/03/00
EDN-Design Ideas: Intelligent sensors and signal conditioners for
plant-automation systems must produce outputs compatible with standard
data-acquisition systems, such as PCs, programmable logic controllers, and remote
terminals for supervisory and control systems.....(design idea added 11/05) |
|
Instrumentation Amp Swings Rail to Rail - 03/03/94 EDN-Design Ideas: You
can combine an instrumentation amplifier and an inexpensive CMOS op amp to get the
better of two worlds: the precision of a bipolar instrumentation amp and the5V
single-supply operation of the CMOS op amp. The characteristics of such a
circuit.....(design idea added 4/02) |

Instrumentation amplifier based current shunt exhibits 0V drop - 11/27/08
EDN-Design Ideas: , A current-to-voltage converter has 0V drop.....(design
idea added 08/09) |

Instrumentation amplifier compensates system offset from single supply -
03/19/09 EDN- Design Ideas, An instrumentation amp operates from one supply
and lets you reset the system offset by applying a positive correction voltage to
the VREF input.....(design idea added 08/09) |
