Application Information
The ISL24201 provides the ability to adjust the VCOM voltage
during production test and alignment, under digital control, to
minimize the flicker of an LCD panel. A digitally controlled
potentiometer (DCP), with 256 steps of resolution, adjusts the sink
a mechanical potentiometer circuit and the equivalent circuit
replacement with the ISL24201.
The output is connected to an external voltage divider, as shown in
Figure 3, so that the ISL24201 will have the ability to reduce the
voltage on the output by increasing the OUT pin sink current. The
amount of current sunk is controlled by the I2C serial interface.

NOTE:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
Electrical Specifications Test Conditions: VDD = 3.3V, AVDD = 18V, RSET= 5kΩ, R1 = 10kΩ, R2 = 10kΩ, (See Figure 5); unless otherwise
specified. Typicals are at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
