A 12 bit A/D converter has an input range of -12 V to 12 V. An amplifier is connected to the input and has selectable gains of 10, 25, 50, 100, 250, and 500. The connected transducer has an output that varies between +75 and -75 mV. Design a simple voltage-divider attenuator using standard resistor values to minimize the quantizing error. What will the quantizing error be when the transducer voltage is 5 mV.
