The amplifier shown was built using an op-amp whose output is capable of swinging up to 0.8V below the positive supply voltage and down to 1.4V above the negative supply voltage. Also, the input common-mode range of the op-amp is from 0.5V below the positive supply voltage to 1.5V above the negative supply voltage. What are the positive and negative supply voltages, respectively?
A) +2.2V, -3.2V
B) +2.9V, -1.6V
C) +1.5V, -0.5V
D) +1.4V, -0.8V
