details.
Integration resistor connection. Use a 47kΩ resistor for a 200mV full scale range
and a 470kΩ resistor for 2V full scale range.
The size of the auto-zero capacitor influences system noise. Use a 0.47μF
capacitor for 200mV full scale, and a 0.047μF capacitor for 2V full scale.
See Section 4.1 “Auto-Zero Capacitor”, Auto-Zero Capacitor for more details.
