I would like to digitalise an analog DC ammeter of 0-750A range using pic16f876a. The voltage across the shunt resistor of ammeter ranges from 0-60mv DC. If I connect this shunt voltage to the input pin of 10 bit Analog to digital convertor of pic then the resolution will be very low. With 5v as reference, 1 division is equal to 4.8mv. So by converting this value to ampere range it will be 4.8*12.5= 60A. So the ampere changes by 60A for each division. ie 60A,120A....etc. I would like to boost the input DC value of 0-60mv to some what near the reference voltage, ie 0-5V. Any body have idea of doing this DC to DC signal boosting without loading the input signal. Please help me ...


Regards
sajeev
