| 11. | An operational amplifier can, if necessary, be forced to act as a comparator.
|
| 12. | A fully differential amplifier is similar to the operational amplifier, but also has differential outputs.
|
| 13. | For very high-frequency circuits, a current-feedback operational amplifier is often used.
|
| 14. | A basic inverting transresistance amplifier can be built from an operational amplifier and a single resistor.
|
| 15. | It was pioneer in the fields of digital-to-analog converters and operational amplifiers.
|
| 16. | An industry milestone was the OP07 which was the first internally compensated three stage operational amplifier.
|
| 17. | In this application, the sum and difference of two input voltages are formed using operational amplifiers.
|
| 18. | In 1963, Fairchild hired Robert Widlar to design analog operational amplifiers using Fairchild's process.
|
| 19. | When using active components, such as operational amplifiers, the differentiation index can be arbitrarily high.
|
| 20. | The magnitude of the output voltage is a property of the operational amplifier and its power supply.
