Hello,
I know that slew rate specifieshow fast the output voltage of an op-amp can change. But is there a measure that specifies how fast the output current of op-amps can change?
I need this information because I need to drive a capacitive load with a triangular voltage waveform. That means the the current waveform will be a square wave that swings from +Iout to -Iout.
I did a simulation with OPA541 and saw that it can it can go from +180mA to -180mA in 2us. But it's an expensive IC so I want to use a cheaper op-amp.
Here are the circuit schematic and simulation results:
