GMT  G1625RD1U TDFN3X3-8 21+

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.
