I need a current source to generate a test signal with max. 4A into 20Ohm load (max. 80V)
The "problem" is that I need to control the shape of the current signal with a voltage signal. The bandwidth of the desired current signal is 50kHz (>20kHz would work).
Energy efficiency is more important than precision (+-10% is ok)
Is there a TI Product / solution for this problem?
