Op Amp Speed Comparison - uA741 vs TL081 - Kinda' Unfair  #electronics #experiment
Channel: More Than Electronics
Date: 2024-02-08

Using a circuit to generate square waves we can see just how much quicker the TL081 is compared to a uA741.  Pin for pin compatible but much better performance from the TL081.  Not just quicker, it has lower distortion and less noise for about the same price.

Rise time is typically defined as the time taken for a voltage to go from 10% of final value to 90% of final value.  Some very fast circuits use 20%-80%.

The square wave generated with the TL081 circuit can be used to adjust the calibration of 10x oscilloscope probes, if your 'scope doesn't have one built in.
