The programming circuit in Figure 5 drives CE high to
enable the CTL input when it is connected. When the
programming circuit is not connected, CE is pulled low
through resistor R
CE
, which disables the CTL input. The
CTL input is relatively immune to noise and brief volt-
age transients. It can be safely left continuously
enabled if higher supply current is acceptable.
VCOM Adjustment (CTL)
Pulse CTL low for more than 200μs to increment the DAC
setting, which increases the OUT sink current and lowers
the VCOM level by 1 least-significant bit (LSB) (Figure 6).
Similarly, pulse CTL high for more than 200μs to decre-
ment the DAC setting, which decreases the OUT sink cur-
rent and increases the VCOM level by 1 LSB.
