Other Parts Discussed in Thread: ADS1256, , ADS1262
Dear all,
after taking a look at ADS1262 datasheet (used on TIPD188), Vref must be positive (pag 41). However, in order to mantain a ratiometric relation togheter with the proposed "ac" excitation, Vref must sometimes be negative (once Vref=VrefP-VrefN and the excitation switchs over time). As I suppose TIPD188 works fine, maybe this is a fault on datasheet. Hence, would it be possible to use the same approach with ads1256?
best regards,
