The analog input required to generate a full scale output (1999 counts). Place
100 mV between Pins 35 and 36 for 199.9 mV full scale. Place 1V between Pins 35
and 36 for 2V full scale. See paragraph on Reference Voltage.
Lamp test. When pulled HIGH (to V+) all segments will be turned on and the display
should read -1888. It may also be used as a negative supply for externally generated
decimal points. See paragraph under TEST for additional information.
See Pin 40.
See Pin 40.
Pins 40, 39, 38 make up the oscillator section. For a 48 kHz clock (3 readings per
section), connect Pin 40 to the junction of a 100 kΩ resistor and a 100 pF capacitor.
The 100 kΩ resistor is tied to Pin 39 and the 100 pF capacitor is tied to Pin 38.
