For example the LM158 is quoted as having 0.3 V/µs which means therefore to go from 0 to 5 V would take 5 / 0.3 = 16.66 µs, which is fairly close to your observations. You can get faster op-amps. | |

This probably would have been a faster, better approach, but if I can do everything in software that would be ideal. | |
