General Description
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.
G1625 includes one time programmable (OTP) memory to store the DAC code on the chip, eliminating the need for external EEPROM. The chip supports up to 100 write operations to OTP memory. G1625 has an I2C interface to set the VCOM reference voltage and write into OTP memory.
