Offset drift can be problematic in high precision applications and cannot be calibrated out during initial manufacturing. In addition to drift over temperature, an amplifier’s input offset voltage can ...

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 ...

The main function of an instrumentation amplifier is the amplification of differential signals while rejecting unwanted common-mode interference. This function proves particularly useful for ...

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 ...

Benefits of using an indirect current-mode instrumentation amplifier for large differential offsets. Design specs for a low-power application. Key design considerations when implementing an in-amp ...

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) ...

How to avoid amplifier output driver saturation when using very low bias current amplifiers with high source impedance sensors, write Jon Munson and Kevin Scott When taking sensor measurements, the ...

Many current-sensing ICs are available for applications that require single-quadrant operation, where positive common-mode voltages are present and current flows in only one direction. There are also ...
