ADC12451CIJ

The ADC12451CIJ is one member of ADC12451 family,the ADC12451CIJ 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 a5V) or a bipolar range (b5V to a5V) can be accommodated with +/-5V supplies.

Features of the ADC12451CIJ can be summarized as:(1)self-calibration provides excellent temperature stability;(2)internal sample-and-hold;(3)8-bit mP/DSP interface;(4)bipolar input range with a single +/-5V reference.It can be used in digital signal processing,audio,telecommunications,high resolution process control and instrumentation.

The absolute maximum ratings of the ADC12451CIJ are:(1)supply voltage (VCC=DVCC=AVCC):6.5V;(2)negative supply voltage(V-):-6.5V;(3)voltage at logic control inputs:-0.3V to (VCC+0.3V);(4)voltage at analog inputs:V- -0.3V) to (VCC + 0.3V);(5)AVCC-DVCC:0.3V;(6)input current at any Pin:+/-5 mA;(7)package input current:+/-20 mA;(8)power dissipation at 25:875 mW;(9)storage temperature range:-65 to +150.If you want to know more information such as the electrical characteristics about this part,please download the datasheet in www.seekic.com and www.chinaicmart.com .
