PRODUCTION DATA
The INA183 features low drift for both the gain error and offset voltage specifications. The low gain error drift of 10 PPM/ºC results from the well matched internal resistor network that sets the device gain. The low offset drift is due to the internal chopping architecture of the amplifier. Input chopping reduces both the offset and offset drift since any change in offset is canceled with each chopping cycle. The maximum input offset drift of the INA183 is 0.5 μV/ºC. The low drift of the gain error and offset voltage provides accurate current measurement over the operational temperature range of -40ºC to 125ºC that exceeds the performance of most discrete current sensing implementations.
