Gamma and VCOM Reference Voltages

General Description

Features

The MAX9665/MAX9666/MAX9667 provide multiple

programmable reference voltages for gamma correc-

tion in TFT LCDs and a programmable reference volt-

age for VCOM adjustment. All gamma and VCOM

reference voltages have a 10-bit digital-to-analog con-

verter (DAC) and buffer with high peak current. This

reduces the recovery time of the output voltage when

critical levels and patterns are displayed.

o 6/8/10 Channels Gamma Correction, 10-Bit

Resolution

o VCOM Driver

o Integrated Multiple-Time Programmable Memory

o DAC Reference Input

o Single-Wire and I²C Programming of VCOM

These devices include multiple-time programmable

(MTP) memory to store gamma and VCOM codes on

the chip, eliminating the need for external EEPROM.

The MTP memory supports up to 300 write operations.

Reference

o 950mA Peak Transient Current on VCOM Channel

The MAX9665/MAX9666/MAX9667 feature an I²C inter-

face to control the programmable reference voltages

and a single-wire interface to toggle the VCOM refer-

ence voltage up or down.
