G1625 Datasheet (GMT) - 7-bit Programmable VCOM Reference

G1625, 7-bit Programmable VCOM Reference

The G1625 provides a programmable reference voltage for TFT-LCD panel VCOM adjustment.

A 7-bit digital-to-analog converter (DAC) detects current from an external resistor-divider to create the VCOM reference voltage.

This voltage is used as the input to a high current drive voltage buffer.
