ADC1241 Self-Calibrating 12-Bit Plus Sign mP-patible A D Converter with Sample-and-Hold November 1994 ADC1241 Self-Calibrating 12-Bit Plus Sign mP-patible A D Converter with Sample-and-Hold General Description The ADC1241 is a CMOS 12-bit plus sign successive approximation analog-to-digital converter On request the ADC1241 goes through a self-calibration cycle that adjusts positive linearity and full-scale errors to less than g LSB each and zero error to less than g 1 LSB The ADC1241 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion The analog input to the ADC1241 is tracked and held by the internal circuitry and therefore...
