Dear all,
One of my cusotmer use OPA4228 to measure current shunt drop out voltage. since there is only one 12V is avaialble, i suggest the customer change the reference voltage to 6V. however, i failed to get any result in TI TINA.
Note, input current is 20kHz, 80Ap-p signal.
My question is
- can this circuit works ?
- what is the minimum Vref in this case ?
many thanks
Hawk Tong
