Product Summary

The ADC1251CIJ is a CMOS 12-bit plus sign successive approximation analog-to-digital converter. On request, the ADC1251CIJ goes through a self-calibration cycle that adjusts for any zero, full scale, or linearity errors. The ADC1251CIJ also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion.
