A common situation, yet undesirable condition, is to have
the input signal of an A/D converter (such as one of Burr-
Brown’s delta-sigma converters) overdrive the input stage.
A possible question that arises in this situation is “What will
the output digital code become if the analog input is
overdriven?” The differential analog input range of the
ADS1210, ADS1211, ADS1212 and ADS1213 analog-todigital
converters, shown in Figure 1, can be configured to
operate in a unipolar or bipolar mode. In the unipolar mode,
the input range is generally 5Vp-p. For bipolar operation the
input range is generally 10Vp-p.
