Other Parts Discussed in Thread: INA282, INA293
Hi, Support Team
1. The load is an electronic load with CC mode and we have also applied a CV on Shunt-Resistor to generate a DC current (all PWMs and Power Stage are stop), the output damping is the same.
2. The pink signal is LLC - transformer primary voltage.
3. we have also adding a RC filter on the output, (180ohm+ 100pF~10nF) and Between PIN1 and PIN 8 add 22pf cap and CSL4 value increase to 220pf but cannot fixed noise issue...
Q1: if current shunt over 1.5A, output noise will be worse. Is about internal switch causes the output noise?
schematic as below chart:
measured as below chart:
INA switch:
if any suggestion, Please advise me.
Thanks,
Best regards,
Lawrence
