●General Description

●The ADC1251 is a CMOS 12-bit plus sign successive approximation analog-to-digital converter. On request, the ADC1251 goes through a self-calibration cycle that adjusts for any zero, full scale, or linearity errors. The ADC1251 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion.

●Features
