V-
Negative power supply voltage.
27
(14)
VINT
The integrating capacitor should be selected to give the maximum voltage swing
that ensures component tolerance buildup will not allow the integrator output to sat-
urate. When analog common is used as a reference and the conversion rate is 3
readings per second, a 0.047
μF capacitor may be used. The capacitor must have a
low dielectric constant to prevent rollover errors. See Section 6.3, Integrating
Capacitor for additional details.
28
(13)
VBUFF
Integration resistor connection. Use a 180k
Ω for a 20mV full scale range and a
1.8M
Ω for 2V full scale range.
29
(12)
CAZ
The size of the auto-zero capacitor influences the system noise. Use a 0.47
μF
capacitor for a 200mV full scale and a 0.1
μF capacitor for a 2V full scale.
See Section 6.1, Auto-Zero Capacitor for more details.
30
(11)
VIN-
The low input signal is connected to this pin.
31
(10)
VIN+
The high input signal is connected to this pin.
32
(9)
ANALOG
COMMON
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 Section 7.3, Analog Common for more details. It also acts as a reference
voltage source.

CREF-
See Pin 34.
