PRODUCTION DATA
Differential input signals are digitized to 12 bits, based on the full-scale range. Signal excursions beyond the full-scale range, that is, greater than +VIN_FSR/2 or less than – VIN_FSR/2, are clipped at the output. An input signal above the FSR results in all 1's at the output; an an input signal that is below the FSR results in all 0's at the output. When the conversion result is clipped for the I-channel input, the out-of-range I-channel (ORI) output is activated so that ORI+ goes high and ORI– goes low while the signal is out of range. This output is active as long as accurate data on either or both of the buses is outside the range of 000h to FFFh. The Q channel has a separate ORQ, which functions similarly.
