Other Parts Discussed in Thread: OPA317, TLV333, LM7705
Hi,
The customer reviews the OPA317 to measure the IGBT current.
However, the offset voltage is high compared to the competitor, so the customer does not want to use OPA317.
With the IGBT not turned on and 0A, OPA317 measures up to 1 mV.
OPA317 : Max 1mV
Competitor : Max 0.2mV
We are applying the same circuit, and please review the circuit to improve the offset voltage of OPA317 and advise us on how to improve it.
