Thank you Olin, I'm much more familiar with digital electronics and I was unaware that a microcontroller solution was a conventional approach to this problem. I'm considering using an STM32 based approach now. I'm guessing that would be a simple ADC system with the signal input (voltage divided to ma... (more) |

The input signals will be scaled very slowly. Ramps from 0-10V will happen over 100's of milliseconds to seconds. The inputs will sustain their level for a while. Changes are infrequent (30 seconds to > 10 minutes)
I'll add this to the question as well. I'll do some more research on microcontrolle... (more) |

| Question | — |
Dual ratiometric power scaler design review and issues I need to make a circuit board that has the following inputs and outputs: Inputs and outputs Inputs: - \$V{\text{in1}}\$ (0-10VDC) PLC controlled signal - \$V{\text{in2}}\$ (0-10VDC) PLC controlled signal - \$V{\text{batt}}\$ (4.8-5.2VDC) battery power. This fluctuates around 5V based ... (more) |
