5. The TM4C123 has a built in 12 bit ADC, A strain gauge sensor signal conditioning application of the ADC is shown in the figure. The op amp is used for gain and to buffer/drive the ADC. Answer the following questions about the sensor application. (20pts) show your work TM4C123 RI 3.3V 3.3V mid supply bias 1 KD 1.65V ADC R AR strain gauge Gain Bandwidth Product GBW-15 MHz Input referred voltage noise n3 Hz R = 1Ω for a 5kg load What type of amplifier configuration is used? a. b. When the load is zero, AR-0, what is the input voltage to the ADC? What value of Rf is needed for the ADC input to be 3.3 volts when there is a 5 kg load? c.
