Web22 de mai. de 2024 · The system slew rate is 45 V/ s. This is the value used to calculate the system power bandwidth, if needed. The first op amp to slew in this circuit is the 411, even though it is about 30 times faster than the 741 used in stage 1. The reason for this is that it must handle signals 32 times as large. Web9 de dez. de 2014 · The op-amp has a 1 uF bypass cap right next to the pin, and a 10 uF cap further away. Both are ceramic. Looking at the supply pin with a scope revealed a fairly smooth supply - it doesn't jitter with these weird spikes. FYI the paralleled resistors are there to increase the overall tolerance of each pair of resistors.
