Negative power supply voltage.
The integrating capacitor should be selected to give the maximum voltage
swing that ensures component tolerance build-up will not allow the integrator
output to saturate. When analog common is used as a reference and the
conversion rate is 3 readings per second, a 0.047
μ
F capacitor may be used.
The capacitor must have a low dielectric constant to prevent roll-over errors.
See Integrating Capacitor section for additional details.
Integration resistor connection. Use a 180 k
for a 200 mV full-scale range
and a 1.8 M
for 2V full-scale range.
The size of the auto-zero capacitor influences the system noise. Use a 0.47
μ
F
capacitor for a 200 mV full scale, and a 0.1
μ
F capacitor for a 2V full scale. See
paragraph on Auto-Zero Capacitor for more details.
The low input signal is connected to this pin.
The high input signal is connected to this pin.
This pin is primarily used to set the analog common-mode voltage for battery
operation or in systems where the input signal is referenced to the power
supply. See paragraph on Analog Common for more details. It also acts as a
reference voltage source.
