Self-calibrating 12-bit Plus Sign A/d Converter With Sample-and-hold

The ADC1251 is a CMOS 12-bit plus sign successive ap- proximation 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 cor- rects 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 re- quired. The ADC1251 has an S/H control input which direct- ly controls the track-and-hold state of the A/D. A unipolar Analog input voltage range (0 to a5V) or a bipolar range (b5V to a5V) CAN be accommodated with g5V supplies. The 13-bit data result is available on the eight outputs of the ADC1251 in two bytes, high-byte first and sign extended. The digital inputs and outputs are compatible with TTL or CMOS Logic levels.
