OK, so the uA741 is 42 years old now. For its time it may have been a great opamp; the requirements weren't as high as today, and there was far less competition. But I was wondering what's the 741's appeal today.
- it's slow. GBW 1MHz, slew rate < 0.5 V/us
- it's not low power, nor low voltage
- it doesn't have low bias current FET inputs
- it doesn't have rail-to-rail inputs or outputs
- it's not low noise
- many more modern opamps have comparable price
Why is the 741 still used today?
