Negative power supply voltage.
Integrator output. Connection point for integration capacitor. See INTEGRATING
CAPACITOR section for more details.
Integration resistor connection. Use a 47 kΩ resistor for a 200 mV full scale range
and a 47 kΩ resistor for 2V full scale range.
The size of the auto-zero capacitor influences system noise. Use a 0.47 µF capacitor
for 200 mV full scale, and a 0.047 µF capacitor for 2V full scale. See Section 7.1
“Auto-Zero Capacitor (CAZ)” on Auto-Zero Capacitor for more details.
The analog LOW input is connected to this pin.
The analog 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. It
also acts as a reference voltage source. See Section 8.3 “Analog Common (Pin
32)” on ANALOG COMMON for more details.
See Pin 34.
A 0.1 µF capacitor is used in most applications. If a large Common mode voltage
exists (for example, the V
used, a 1 µF capacitor is recommended and will hold the rollover error to 0.5 count.
