1CINT
Integrator capacitor connection.
2V-
Negative power supply.
3CAZ
The Auto-zero capacitor connection.
4
BUF
The Integrator resistor buffer connection.
5
AGND
This pin is analog ground.
6C-REF
Negative reference capacitor connection.
7C+REF
Positive reference capacitor connection.
8V-REF
External voltage reference (-) connection.
9V+REF
External voltage reference (+) connection.
10
V-IN
Negative analog input.
11
V+IN
Positive analog input.
12
A
Converter phase control MSB Input.
13
B
Converter phase control LSB Input.
14
COUT
Comparator output. COUT is HIGH during the Integration phase when a positive input voltage is being integrated and
is LOW when a negative input voltage is being integrated. A HIGH-to-LOW transition on COUT signals the processor
that the Deintegrate phase is completed. COUT is undefined during the Auto-Zero phase. It should be monitored to
time the Integrator Zero phase.
15
DGND
Digital ground.
16
V+
Positive power supply.
