(15)
V–
Negative power supply voltage.

(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 saturate. When analog common is used as a reference and the
conversion rate is 3 readings per second, a 0.047
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.
28
(13)
VBUFF
Integration resistor connection. Use a 180k
for a 20 mV full-scale range and
a 1.8M
for 2V full-scale range.
29
(12)
CAZ
The size of the auto-zero capacitor influences the system noise. Use a 0.47
F
capacitor for a 200mV full scale, and a 0.1
F capacitor for a 2V full scale. See
paragraph on 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
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.
