TYPICAL APPLICATION
The Application Circuit (Figure 1) shows the connections for a typical application when
using a 12 digit (7 segment) display, plus decimal points.
On-Chip LCD Voltage Divider Disable
The integrated divider for the LCD voltages can be disabled by applying a high level
on the EN input (EN = 1).
Contrast Setting
The contrast may be adjusted by applying an external LCD voltage on input V1, with
the internal voltage divider activated.
Oscillator
The on-chip oscillator circuit requires one external capacitor for operation. The
capacitor value is calculated as follows:
C = 7µF.1Hz/f
f = Required oscillator frequency
The backplane multiplex rate is f/8 for 4-backplane mode and f/6 for 3-backplane
mode.
