General Description
The MAX1512 is a programmable VCOM-adjustment
solution for thin-film transistor (TFT) liquid-crystal displays
(LCDs). The MAX1512 simplifies the labor-intensive
VCOM-adjustment process and replaces mechanical
potentiometers, which significantly reduces labor costs,
increases reliability, and enables automation.
The MAX1512 attaches to an external resistive voltage-
divider and sinks a programmable current to set the
VCOM voltage level. An internal 7-bit digital-to-analog
converter (DAC) controls the sink current. The DAC is
ratiometric relative to AVDD and is guaranteed to be
monotonic over all operating conditions. This VCOM
calibrator IC includes an EEPROM to store the desired
VCOM voltage level. The EEPROM can be programmed
repeatedly, giving TFT LCD manufacturers the flexibility
to calibrate the display panel as many times as the
manufacturing process requires.
The IC features a single-wire interface between the
LCD panel and the programming circuit. The single-
wire interface delivers both programming power and
DAC-adjustment commands to minimize changes to
MAX1512 is available in an 8-pin 3mm x 3mm TDFN
package. A complete evaluation kit is available to sim-
plify evaluation and production development.
