      CXLC8981 CXLC8982 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. CXLC8981 CXLC8982 has an I 2 C interface to set the VCOM reference voltage and write into OTP memory.The CXLC8981 CXLC8982 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.
