Hi Brian,

Are you looking for data used to construct the GE versus Temperature plot? If so you would have to read it off of the plot itself.

On the other hand, mass production data at temperatures other than room doesn’t exist. However GE is bound by the electrical spec, and can be calculated (room temp + temperature drift).

Hello Guang,

Customer would like to get the exact number Gain Error % at -15degree and 60degree for the system's worse case estimation. Please offer them with INA240A2 and INA241A3. Appreciate!!

Hi,

For design limits, we shouldn’t read off of typical curves. Calculation should be done based on the electrical specification table.

Anyway, the worst case gain error would be ±0.21% over the specified range of -15 to 60˚C range.

Regards, Guang
