12-bit Plus Sign Sampling A/d Converter - National Semiconductor

The ADC1242 is a CMOS 12-bit plus sign successive ap- proximation Analog-to-digital converter. On request, the ADC1242 goes through a self-calibration cycle that adjusts positive linearity error to less than g1 LSB full-scale error to less than g3 LSB, and zero error to less than g2 LSB. The ADC1242 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion. The Analog input to the ADC1242 is tracked and held by the internal circuitry, and therefore does not require an external sample-and-hold. A unipolar Analog input voltage range (0V to a5V) or a bipolar range (b5V to a5V) CAN be accom- modated with g5V supplies. The 13-bit word on the outputs of the ADC1242 gives a 2s complement representation of negative numbers. The digi- tal inputs and outputs are compatible with TTL or CMOS Logic levels.
