Hello Jonathan, There are several options that do not require a low voltage (<5V) TVS. Figure 65 in the datasheet suggests adding diode clamps at the ADC inputs. The BAT54 is usually a good choice for these applications. When adding current steering diodes, you should also consider adding a TVS to the power supply rails, as many voltage regulators cannot sink current and you could cause the supply rails to exceed ABS max specs, resulting in system damage. Another approach is to use a TVS at a higher voltage, and series input resistors to limit current into the internal diode clamps (ADS1282 internal diodes can handle up to 10mA continuous). The following TI Precision Labs discusses this approach. In fact, simply adding higher value input resistors may improve EOS (electrical over stress) enough to prevent damage. The maximum resistance will depend on input leakage current of the ADC and allowable system errors. https://www.ti.com/content/dam/videos/external-videos/en-us/9/3816841626001/6303631504001.mp4/subassets/slides-protecting-delta-sigma-input-circuit-operation.pdf Regards, Keith Nicholas Precision ADC Applications
