Negative power supply.

Integrator amplifier output. To be connected to integrating capacitor.

Input buffer amplifier output. To be connected to integrating resistor.

Integrator amplifier input. To be connected to auto-zero capacitor.

Differential inputs. To be connected to input voltage to be measured. LO and HI

designators are for reference and do not imply that LO should be connected to

lower potential, e.g., for negative inputs IN LO has a higher potential than IN HI.

Internal voltage reference output.

Connection pins for reference capacitor.

Power Supply.

Display test. Turns on all segments when tied to V+.

Device clock generator circuit connection pins.
