The 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 a 5V) or a bipolar range (b5V to a 5V) can be accommodated with g 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 |
