Designers now have available a broad collection of instrumentation amplifier (in-amp) design circuits for dual supplies. However, there also is a growing use of the single-supply amps, especially in ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Instrumentation amplifiers (INA) can sometimes throw you a curve ball for even the easiest applications. One would use an INA to gain a small differential signal to a usable voltage level in ...

These days there a large number of sensors and analog circuits that are “controller friendly” meaning that their output signal is easily interfaced to the built-in Analog to Digital Convertors (ADCs) ...

Instrumentation amplifiers are amplifiers that measure small signals in noisy environments. Also known as in amps, these devices employ a technique called common-mode rejection (CMR) to distinguish ...

The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...

The ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...
