A 0.1μF capacitor is used in most applications. If a large Common mode voltage
exists (for example, the V
used, a 1μF capacitor is recommended and will hold the rollover error to
0.5 count.
Positive Power Supply Voltage.
The analog input required to generate a full scale output (1999 counts). Place
100mV between Pins 32 and 36 for 199.9mV full scale. Place 1V between
Pins 35 and 36 for 2V full scale. See Section 4.6 “Reference Voltage”, Refer-
ence Voltage.
Lamp test. When pulled HIGH (to V+), all segments will be turned on and the dis-
play should read -1888. It may also be used as a negative supply for externally
generated decimal points. See Section 3.1.7 “Test”, TEST for additional infor-
mation.
See Pin 40.
See Pin 40.
Pins 40, 39, 38 make up the oscillator section. For a 48kHz clock (3 readings per
section), connect Pin 40 to the junction of a 100kΩ resistor and a 100pF capaci-
tor. The 100kΩ resistor is tied to Pin 39 and the 100pF capacitor is tied to Pin 38.
