NUMBER
FUNCTION
INN
1
Negative input of the op amp. To create a unity-gain VCOM voltage buffer, connect this pin to the VCOM_OUT pin.
DVR_OUT
2
Current Sink Output. The sink current into the DVR_OUT (Digital Variable Resistor) pin is equal to the DAC setting times the maximum
adjustable sink current divided by 256. See the “SET” pin function description (pin 9) for setting the maximum adjustable sink
current.
AVDD
3
High-Voltage Analog Supply. Bypass to GND with 0.1F capacitor.
DNC
4
Do Not Connect to external circuitry. It is acceptable to ground this pin.
GND
5
Ground connection.
VDD
6
Digital power supply input. Bypass to GND with 0.1F capacitor.
CTL
7
Up/Down Control for internal counter and Internal EEPROM Programming Control Input. When CE is high:
A low-to-mid transition increments the 8-bit counter, adding 1 to the DAC setting, increasing the DVR_OUT sink current, and
lowering the divider voltage at the DVR_OUT pin.
A high-to-mid transition decrements the 8-bit counter, subtracting 1 from the DAC setting, decreasing the DVR_OUT sink current,
and increasing the divider voltage at the DVR_OUT pin.
To program the EEPROM, take this pin to >4.9V (see “CTL EEPROM Programming Signal Time” in the “Electrical Specification”
table on page 5 for details). Float when not in use.
