Other Parts Discussed in Thread: INA190
we need a programmable current source 1..12mA (2..24V), 50kHz for IEPE sensors
with over voltage protection up to ± 100V
we built 3 prototypes with this circuit.
The gain is different for all 3 prototypes (between 17 and 22)
In the "Application Information" the shunt resistor is in the mΩ range. Could this be the reason for the gain deviation?
Thanks for your support!
