When using the burn-out current sources, be aware of the offset error caused by the currents flowing through impedances in the input path, including the multiplexer resistance RMUX), external filter resistors and the internal impedance of the sensor REXT), as shown in Figure 96. In many cases, the offset error can be calibrated. Be aware that the combination of chop mode and high data rates increases the input current to the PGA. The increased input current can affect the accuracy of the burn-out current sources.
