Special Considerations
To connect a high-value resistor between the positive input and +5V, refer
to the Accuracy and Resolution Considerations section of Chapter 5,
Adding Components for Special Functions.
To reduce noise by connecting a lowpass filter to the analog inputs of the
SCB-68, refer to the Lowpass Filtering section of Chapter 5, Adding
Components for Special Functions.
