I'm trying to create a constant current LED driver. I have found and read information about the miller effect and came up with the schematic below.
What are the most important parameters for choosing the Opamp? Is this the Slew Rate, Gain Bandwidth Product, or any of the other specifications?
I was looking at an Opamp and power it with ±15 Volt since the MOSFET has a maximum VGS of ±20 Volt.
UPDATE: I was thinking of a opamp like this one BA4580YFVM-MGTR
- Frequency: 1-100 Hz
- Pulse duration: 100-300 us
- If: 1A during pulse
