Excersie 3.3.3 Use of amplifiers in microcontrollers
In the Application Notes 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 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?
