DESCRIPTION
The BUF08800 reference generator offers eight program-
mable 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 V
COM
.
All gamma/V
COM
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 V
COM
driver features up to 400mA peak
current drive. V
COM
voltage compensation at different
locations on the LCD panel can be accomplished using the
negative input of the integrated V
COM
op amp.
The Gate High and Low voltages can differ because of
changes in panel size or technology. The BUF08800
supports digital adjustment circuits for the gate voltages.
This feature enables the adjustment of gate voltages
through software without changing hardware, thus
reducing development time and risk.
The BUF08800 is manufactured using Texas Instruments’
proprietary, state-of-the-art, high-voltage CMOS process.
This process allows very dense logic as well as high
supply voltage operation of up to 22V.
The BUF08800 is available in a small TSSOP-20
PowerPad
package, and is specified from 40
°
C to
+85
°
C.
