G1625 Description
The G1625 provides a programmable reference voltage for TFT-LCD panel V adjustment. A 7-bit digital-to-analog converter (DAC) detects current from an external resistor-divider to create the V reference voltage. This voltage is used as the input to a high current drive voltage buffer.
