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