I have questions regarding gain setting of INA317.
Would you answer following questions?
- Is there any recommended way of changing Rg?
- We think use digipot or switching register array by some switch. Is there any concern regarding this method?
- Could I change Rg when the case of input signal is still remained and power is supplied to INA317?
- Is there any instrumentation device which can change gain digitally? For example, using I2C or SPI, using selecting pin status as binary, etc...
I'm looking forward to hearing back from you.
