BUF08800 Programmable Reference Generator with Digital Gate-Voltage Adjustment
The BUF08800 reference generator offers eight programmable reference channels that can be used depending on the application needs. For example, all eight channels can be used for gamma correction, or some as gamma references and some to digitally adjust the gate voltages or VCOM.
All gamma/VCOM channels swing to within 100mV of the positive or negative supply rail with a 10mA load. All channels are programmed using a standard two-wire interface that supports standard operation up to 400kHz and also high-speed data transfer up to 3.4MHz.
The integrated VCOM driver features up to 400mA peak current drive. VCOM voltage compensation at different locations on the LCD panel can be accomplished using the negative input of the integrated VCOM op amp
