ADC1251 - Self-Calibrating 12-Bit Plus Sign A/D Converter
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 e

ADC1251 Self-Calibrating 12-Bit Plus Sign A D Converter with Sample-and-Hold
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 The analog input to the ADC1251 is tracked and held by the internal circuitry so an external sample-and-hold is not required The ADC1251 has an S H control input which directly controls the track-and-hold state of the A D A unipolar analog input voltage range (0 to a 5V) or a bipo
