I. Device Description

A. General

The MAX9672/MAX9673/MAX9674 output 12/14/16 voltage references for gamma correction in TFT LCDs and one voltage reference for VCOM. Each

gamma reference voltage has its own 10-bit DAC and buffer to ensure a stable voltage. The VCOM reference voltage has its own 10-bit DAC and an

amplifier to ensure a stable voltage when critical levels and patterns are displayed. The MAX9672/MAX9673 MAX9674 feature integrated multiple-time

programmable (MTP) memory to store gamma and VCOM values on the chip, eliminating the need for external EEPROM. The

MAX9672/MAX9673/MAX9674 support up to 300 write operations to the on-chip nonvolatile memory. The gamma outputs can drive 200mA peak

transient current and settle within 1µs. The VCOM output can provide 600mA peak transient current and also settles within 1µs. The analog supply

voltage range extends from 9V to 20V, and the digital supply voltage range extends from 2.7V to 3.6V. Gamma values and the VCOM value are

programmed into registers through the I²C interface.
