Dear Sir
I would like to measure current with INA169 from my system with the following specifications: Imax = 200A; Vmax = 55V. The desired full-scale output voltage is 5V (ADC input). I'm using a 0.25mOhm shunt resistor (two 0.5mOhm resistors in parallel) and a 100kOhm RL resistor.
When i had make my first tests i notice that the output voltage is around 11V when I have a input current is only 3A.
Have any solution could to solve my problem?
Thanks
======================================================
I'm using the following components:
* INA169
* RS: 2 x 0.5mOhm (10W, 1%)
* RL: 100kOhm (250mW, 0.1%)
* CL: 0.1uF (output filter)
