Testing it out with a voltage of 1.2 V at V
Of course, accomplishing this requires supply voltages in excess of +/− 12 V for the op-
amps. Another option is to offset the input prior to amplifying the voltage.
Consider the differential amplifier in Figure 6-11.
amplifies the difference between the two input voltages.
The formula for this configuration is:
where V
voltage of 1.2V from the sensor, relating to a temperature of 120 °F:
