<panel type="info" title="Excersie 3.3.3 Use of amplifiers in microcontrollers"> <WRAP group><WRAP column 2%>{{fa>pencil?32}}</WRAP><WRAP column 92%> 

In the Application Notes [[http://ww1.microchip.com/downloads/en/appnotes/90003132a.pdf|MTP3132]] from the manufacturer Microchip, a block diagram is given on the 2nd page, which explains the use of the operational amplifier module of various PIC controllers.

  - The logic input signal "$\rm UG$" is shown in the block diagram. What happens in the logic circuit when it takes the value TRUE?
  - Which operational amplifier circuit does this set?
  - For what purpose is this adjusted op amp circuit used?
  - The microcontroller [[http://ww1.microchip.com/downloads/en/DeviceDoc/40001652D.pdf|PIC16F527]] uses the explained op amp: in the microcontroller are 2 op amps $\rm OP1$ and $\rm OP2$. at which pin of the microcontroller can these be found?
