10 / 22 page ES5136 3 1/2 DIGIT A/D CONVERTER W/LCD(Low power) 10 4.Phase 4, Zero Integrate (ZI) During zero integrating, the reference capacitor is charged to the reference voltage and input low is shorted to analog common. At the same time, a feedback loop is closed around the system to input high to cause the integrator output to return to zero so that the overrange hangover of the integral capacitor can be eliminated. 5.Differential Input The input voltage can be any differential voltages, but must be within the common mode range of the input amplifier(buffer). The voltage range is from 0.5 volts below the positive supply to 1.0 volt above the negative supply. In this range the CMRR of the system is 86dB typical. Since the integrator swings with the common mode voltage, it must be assured that the integrator output does not saturate. 6.Differential Reference The reference inputs are floating, and the only restriction on the applied voltage is that it should lie in the range of the owner supply voltage of the converter. The roll- over voltage caused by the reference capacitor losing or gaining charge to stray capacity on its nodes is the main source of common mode error. In a large common mode condition, the reference capacitor will gain extral charge(increase voltage)when deintegrates a positive signal but lose charge(decrease voltage)when deintegrates a negative input signal. The difference in reference for positive or negative input signal will give a roll-over error. By selecting the reference capacitor large enough in comparison to the stray capacitance, this error can be held to less than 0.5 count for the worst case condition. |
