ADC12451 DescriptionThe ADC12451 is a CMOS 12-bit plus sign successive approximation analog-to-digital converter whose dynamic specifications (S/N, THD, etc.) are tested and guaranteed. On request, the ADC12451 goes through a self-calibration cycle that adjusts linearity, zero and full-scale errors. The ADC12451 also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion. The analog input to the ADC12451 is tracked and held by the internal circuitry, so an external sample-and-hold is not required. The ADC12451 has a S#/H control input which directly controls the track-and-hold state of the A/D. A unipolar analog input voltage range (0V to +5V) or a bipolar range (-5V to +5V) can be accommodated with ±5V supplies. The 13-bit data result is available on the eight outputs of the ADC12451 in two bytes, high-byte first and sign extended. The digital inputs and outputs are compatible with TTL or CMOS logic levels.
