REF
A 0.1
F capacitor is used in most applications. If a
large, common-mode voltage exists (e.g., the VIN
– pin is
not at analog common), and a 200mV scale is used, a 1
F capacitor is recommended and will hold the roll-over
error to 0.5 count.

REF
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 32 and 36
for 2V full scale. See paragraph on Reference Voltage.

TEST
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 Test paragraph for more
details.

OSC1
Pins 40, 39 and 38 make up the oscillator section. For
a 48kHz clock (3 readings per sec), connect pin 40 to
the junction of a 100k
resistor and a 100pF capacitor.
The 100k
resistor is tied to pin 39 and the 100pF
capacitor is tied to pin 38.
