Hi all,
I am trying to do a load module that is capable of doing 100~640A load step @ 1600A/us
I am doing 16 individual load cells , and each of them is helping with 40A peak and ~ 10A TDC.
2 of the load cell will be grouped into a load bank, and we will have 8 load bank current reporting to the MCU(due to limited channel)
I am trying to avoid using the summing amplifier at current sense stage (since i have to combine 2 current signals from the 2 CSR into 1 so i can report back to the MCU) and is trying to combine 2 load cells CSR reading through 1 current sense amplifier.
My question is, will this work? will the 2 opamp fights eachother because one opamp can clearly affect the current sense read back , and thus cause another opamp to take action, and may ended up in oscillation ?
thank you
Regards,
Li
