General Description

The AAT1301 is a programmable VCOM buffer for TFT LCD panel application. VCOM voltage can be adjusted and recorded by I2C interface in this device. In addition, users may also set VCOM voltage with 7-Bit accuracy (128 steps). To make AAT1301 an even easier component to use, all programmed settings can be stored in the EEPROM and recalled during power-up.
