@copilot can I do this connection inodre to monitor the voltage through both MCu1 and MCu2?

To provide a specific answer, I would need to know the details regarding MCu1 and MCu2, such as their designators and what pins you intend to use for voltage monitoring. However, given the context of your project and assuming you want to use U1 and U2 as analog voltage monitors (since they are operational amplifiers and you've not mentioned any microcontrollers explicitly in your project description), here's a general approach to monitor voltage:
  1. Voltage Divider Configuration: If you are looking to monitor a voltage higher than what U1 and U2 can directly handle on their input pins, a voltage divider can be used. This can be set up using resistors (for example, R1, R2, R3, and R4 in your project), and then the output of the voltage divider can be fed into the input of your operational amplifiers (U1 and U2).
  2. Connecting to Operational Amplifiers for Voltage Monitoring:
    • You would configure U1 and U2 in a voltage follower (buffer) configuration or another appropriate configuration depending on your requirements. This would involve connecting the output of the voltage divider to the non-inverting input (+IN) of U1 and U2, and then configure the rest of the pins appropriately.
Assuming you meant to use U1 as MCu1 and U2 as MCu2, the specific connections might look something like this for a simple voltage monitoring scenario:
  • Voltage Divider to U1 for Simplified Monitoring:
    • Connect the output of your voltage divider to U1:+IN A (pin 3). The non-inverting input can directly measure the divided voltage.
    • Connect U1:-IN A (pin 2) to U1:OUT A (pin 1) to configure U1 in a buffer configuration.
    • Ensure U1:V+ (pin 8) and U1:V- (pin 4) are connected to the power supply and ground, respectively, which might already be set through nets 7d350720546182762b25d8e9d9fdb8aa and 8363d7e1fec57ab3cd99dccbc58a875e.
  • Voltage Divider to U2 for Simplified Monitoring:
    • Connect the output of your voltage divider to U2:+IN A (pin 3). The non-inverting input can similarly measure the divided voltage.
    • Connect U2:-IN A (pin 2) to U2:OUT A (pin 1) to configure U2 as a buffer.
    • Ensure U2:V+ (pin 8) and U2:V- (pin 4) are connected to the power supply and ground, respectively, possibly through net 709dc2fad0e611ad0eaeb0490d038b6d.
Please note that this is a generalized suggestion based on the assumption that you were referring to using U1 and U2 for voltage monitoring. If MCu1 and MCu2 refer to microcontrollers that are not listed in your provided project components, or if you have specific pins on these microcontrollers intended for ADC (Analog to Digital Converter) input for voltage monitoring, kindly provide more details so that a more accurate set of connections can be suggested.

@copilot yes the output of the opamps would feed into the MCu1 and Mcu2 analog pins

If the output of the operational amplifiers U1 and U2 are intended to feed into analog pins of two microcontrollers (MCU1 and MCU2), here is a suggested approach for connecting these components for voltage monitoring purposes. Since the specific microcontrollers and their corresponding analog pins weren't mentioned, I'll assume generic analog input pins for MCU1 and MCU2:
Connection Strategy:
  1. Operational Amplifiers Setup:
    • Since your intention is to monitor voltage using U1 and U2, you might be using them in a configuration suitable for your application (e.g., non-inverting amplifier, inverting amplifier, etc.). For a simple voltage monitoring, a buffering configuration (voltage follower) is often used to not load the measured point while providing a buffered output to the MCU analog pins.
  2. MCU Connections:
    • Connect U1:OUT A and U1:OUT B to the respective analog input pins of MCU1. This assumes U1 operates in configurations that prepare the voltage levels appropriately for MCU1's analog input range.
    • Similarly, connect U2:OUT A and U2:OUT B to the respective analog input pins of MCU2, under the same assumption for appropriate operation with MCU2.
Example (using a simple buffer configuration):
  • Connect U1 to MCU1:
    • Assuming a simple voltage follower setup for U1:
      • Connect U1:OUT A to MCU1:Analog Pin X. This is where MCU1 will read the voltage level processed by U1.
      • You'll configure U1:-IN A and U1:+IN A as required for your circuit; in a voltage follower, these would be connected together, and to the voltage you're measuring.
    • If U1:OUT B is also used, connect it to another analog pin of MCU1, with a similar setup for U1:+IN B and U1:-IN B.
  • Connect U2 to MCU2:
    • Assuming a similar setup for U2:
      • Connect U2:OUT A to MCU2:Analog Pin Y. This allows MCU2 to read the voltage level processed by U2.
      • U2:-IN A and U2:+IN A would typically be connected in a voltage follower configuration, based on the aspect of the voltage you're monitoring with U2.
    • And if U2:OUT B is also used, it would be connected to another analog pin on MCU2, with U2:+IN B and U2:-IN B configured similarly.
Important Considerations:
  • Voltage Levels: Ensure the output voltage levels from U1 and U2 are within the acceptable range for the MCU's analog inputs. Otherwise, you may require voltage level shifting or attenuation.
  • Decoupling: It might be beneficial to place decoupling capacitors near the analog inputs of the MCUs to help filter out noise.
  • Safety: Implement protection mechanisms if the source voltage could exceed safe levels, especially during abnormal conditions.
Without specifics on MCUs and their pinouts, these recommendations are generalized and aim to guide you on connecting the operational amplifiers to the microcontrollers for analog voltage monitoring. If there are particular constraints or additional requirements for the MCUs, adjustments to this suggestion may be needed.
