Hello Murthy,

Please note the error you will get from the input filtering. Also why use the second stage gain and not use the gain of 50 options? Another suggestion is you could use the INA293 or the INA290 which will have better accuracy.

Also the INA290 and INA293 do not have the under 20mV input voltage error explained in the INA193 device.

The INA281 and the INA280 are also good options.
