In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...
The sketch below shows a single op-amp configured as a variable gain differential amplifier that uses only one variable resistance as a gain adjustment and which maintains, if not a superb value, at ...
Instead it forms a pair of sample-and-hold amplifiers, alternately trimming its own offset as a differential amplifier and then trimming the offset of the other op-amp which does the amplification.
The op-amp is a differential amplifier, sensitive to the difference in potential between the + and – inputs. A comparator IC (e.g; LM.339) is really just a specialized op-amp that has been ...
The op amp — short for operational amplifier — is a packaged differential amplifier. The ideal op amp — which we can’t get — has infinite gain and infinite input impedance.
For instance, if an op amp uses ±5-V supplies, the output can swing over the full range from – 5 V to + 5 V or 10 V. For a single-supply op amp, the range would be 0 to + 5 V.
Designers can replace three operational amplifiers with one fully differential device from the company's THS41xx family and eliminate the need for precisely matched resistors. This new family of ...
The new op amps, claims TI, block most of the common-mode noise and give the devices low total harmonic distortion (THD). The best THD among the devices in the family is -83 decibels (dB) at 1 MHz.
The three op amp INA architecture can perform this function, with the input stage providing a high input impedance and the output stage filtering out the common mode voltage and delivering the ...
STMicroelectronics has introduced a 2.1MHz bandwidth low-side current-measurement amplifier in a 6-lead SOT23 pacakge. Dubbed TSC1801, it is aimed at motor control, solar power and automotive power ...
