what are all ways to interface the op amp to 8051 microcontroller The 8051 neither knows nor cares what is connected to its inputs - all that matters is that they observe the requirements stated in the Datasheet for the specific chip. Remember that standard 8051 ports are Digital; that is, they recognise only two input states - commonly designated '1' for a high level, and '0' for a low level. Again, the Datasheet will specify precisely what constitutes a '1', and what constitutes a '0' - so you just have to design your op-amp circuit to ensure that it delivers those conditions, and only those conditions. |
