MAX1512 - EEPROM-Programmable TFT VCOM Calibrator

General Description

The MAX1512 is a programmable VCOM-adjustment solution for thin-film transistor (TFT) liquid-crystal displays (LCDs).

Key Features

  • a single-wire interface between the LCD panel and the programming circuit. The singlewire interface delivers both programming power and DAC-adjustment commands to minimize changes to panel connectors and production equipment. The MAX1512 is available in an 8-pin 3mm x 3mm TDFN package. A complete evaluation kit is available to simplify evaluation and production development. Features.
  • 7-Bit Adjustable Sink-Current Output.
  • Resistor-Adjustable Full-Scale Range.
  • Guarantee.

Calibrator 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 voltagedivider 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
