Other Parts Discussed in Thread: INA190
Hi,
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!
Best regards,
Alen
