DescriptionThe ADC1251CIJ is a CMOS 12-bit plus sign successive approximation analog-to-digital converter. On request,the ADC1251CIJ goes through a self-calibration cycle that adjusts for any zero, full scale, or linearity errors. The ADC1251CIJ also has the ability to go through an Auto-Zero cycle that corrects the zero error during every conversion.
The analog input to the ADC1251CIJ is tracked and held by the internal circuitry, so an external sample-and-hold is not required.The ADC1251CIJ has an S/H control input which directly 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 ADC1251CIJ in two bytes, high-byte first and sign extended.The digital inputs and outputs are compatible with TTL or CMOS logic levels.The ADC1251CIJ has six features.The first one is self-calibration provides excellent temperature stability.The second one is internal sample-and-hold.The third one is 8-bit P/DSP interface.The fourth one is bipolar input range with a single a5V reference.The fifth one is no missing codes over temperature.The sixth one is TTL/MOS input/output compatible.
Life support devices or systems are devices or systems which, (a) are intended for surgical implan into the body, or (b) support or sustain life, and whose failure to perform, when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
