LM8342 Datasheet (Texas Instruments) - Programmable TFT Calibrator

LM8342, Programmable TFT Calibrator

The LM8342 is an integrated combination of a nonvolatile register (7 bits EEPROM) and a DAC controlled current source.

Using the LM8342, the VCOM calibration procedure is simplified by elimination of the potentiometer adjustment task.

This adjustment task is currently performed at the factory using
