Analog Devices Inc. introduces a zero-drift, digitally-programmable instrumentation amplifier (in-amp). Rated over an extended industrial temperature range, the AD8231 is suited for a variety of ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

Three-op-amp instrumentation amplifiers have long been the industry standard for precision applications that require high gains and/or high CMRR. However, these amplifiers have serious limitations ...

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 ...

In the past, the term instrumentation amplifier (INA) was often misused, referring to the application rather than the device’s architecture. INAs are related to op amps, in that they’re based on the ...

This 126-page guide helps engineers select, evaluate, and design the most appropriate in-amps for specific applications by covering a wide range of topics including... This 126-page guide helps ...

Phase sensitive or lock-in amplifiers can extract low level signals in the presence of relatively high noise and, recently, there has been growing interest in their use in portable or embedded ...

We believe that changes will force amplifier manufacturers to make a greater variety of products having characteristics tailored to the specific application. We've already seen that as voltages drop, ...
