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 ...

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 ...

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 ...

An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...
