| 11. | Many otherwise good power amplifier designs have been found to have inadequate slew rates, by modern standards.
|
| 12. | For example, the general purpose TL081 op-amp has a slew rate of 13 V per microsecond.
|
| 13. | This example used a fixed mounted flywheel sized to result in a 1 / 2 Hz per second slew rate.
|
| 14. | Typical higher performance gradients have a slew rate of up to 100 200 T�m " 1 �s " 1.
|
| 15. | However, it is more common for op-amps to have slew rates in the range 5-100 V per microsecond.
|
| 16. | Slew rate helps us identify the maximum input frequency and amplitude applicable to the amplifier such that the output is not significantly distorted.
|
| 17. | Thus it becomes imperative to check the datasheet for the device's slew rate before using it for high-frequency applications.
|
| 18. | ;Slewing : The amplifier's output voltage reaches its maximum rate of change, the slew rate, usually specified in volts per microsecond.
|
| 19. | After 10x amplification, the output should be a 10 V, 100 kHz sawtooth, with a corresponding slew rate of 1 V per microsecond.
|
| 20. | If the second stage has an effective input capacitance C and voltage gain A _ { 2 }, then slew rate in this example can be expressed as:
