7-Bit, Programmable V Reference with 30x MOTP Memory
General Description
The MAX9660 provides a programmable reference voltage for V adjustment in TFT-LCD panels. A 7-bit, current digital-to-analog converter (DAC) sinks current from an external resistor-divider string to create the V reference voltage, which then serves as the input to a voltage buffer capable of driving out high current.
The MAX9660 includes multiple one-time programmable (MOTP) memory to store the DAC code on the chip, eliminating the need for external EEPROM. The chip supports up to 30 write operations to MOTP memory. The MAX9660 has an I2C interface to set...
