Hi Teams,

What is the impact on detection if SN and SP are reversed in connection? Thanks.

    Che,

    The CSA is bidirectional, so this will simply change the polarity of the CSA output. Instead of mid-point at zero current and CSA increasing output as current increases, the CSA output would instead decrease from the mid-rail by the same magnitude.

    Regards,
