The input overvoltage precautions as described in the ESD Diodes section. If an overvoltage condition occurs on an unused channel, the overvoltage channel may crosstalk to the measurement channel. One solution, as shown in Figure 97, is to externally clamp the inputs with low-forward voltage diodes. The external diodes shunt the overvoltage current flow around the ADC inputs. Be aware of the reverse leakage current that can cause measurement errors.
