A flow sensor produces an output voltage, vs. The output of the sensor is sampled by a data acquisition board with a 16-bit single-ended analog input channel and a digitization range of -5V. What is the digitization range of the data acquisition board? 1) -5V to 5V 2) -10V to 10V 3) -2.5V to 2.5V 4) -8V to 8V
