Figure 2 shows a typical INA application, where the common mode is at midsupply, and the differential input is in millivolts. Also, note that the reference pin is driven to midsupply. It is important ...

Since the dawn of time—or at least since the dawn of precision electronics—a major headache for analog designers has been CMV (common-mode-voltage)-induced errors, also known as the dreaded ground ...

Common-mode rejection is the ability of the differential amplifier (which sits between the oscilloscope and probes as a signal-conditioning preamp) to eliminate the common-mode voltage from the output ...

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 ...

Linear Technology introduces the LT6375, a unity-gain difference amplifier with integrated precision matched resistors. Linear Technology introduces the LT6375, a unity-gain difference amplifier with ...

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

Advancements in power conversion components have far outpaced the ability to accurately measure and characterise these designs. Engineers working on power device designs involving GaN and SiC ...
