description
The BUF11702 is a 10+1-channel buffer targeted
toward the needs of modern high resolution LCD
panels. These high resolution LCD panels are driven by external LCD source drivers, which require a varying
number of references. Due to nonideal characteristics of the LCD panels, the LCD source drivers must produce
nonlinear voltages to the LCD panel. This is called gamma-correction.
Buffers 1 through 10 have output voltage drive characteristics matched to the gamma correction voltage/current
requirements of these panels and are used to drive the reference inputs of the LCD source drivers. All outputs
can swing very close to both rails, but the actual limits are determined by the individual channel’s input offset
voltage, common-mode input range, and load current being delivered. The input/output characteristics have
been set at commonly requested levels.
The V
COM
channel has increased output drive capability to meet the drive requirements of the common-node
of these panels.
The BUF11702 is available in the 28-pin PowerPAD
package that enables it to meet the power handling
requirements of driving these load currents at the required voltage levels.
A flow through pin out has been adopted to allow simple PCB routing and maintain the cost effectiveness of this
solution.
Each buffer is capable of driving heavy capacitive loads and offers fast load current switching, often necessary
when used to drive large LCDs.
All inputs and outputs of the BUF11702 incorporate internal ESD protection circuits that prevent functional
failures at voltages up to 2000 V as tested under MIL-STD-883C Method 3015; however care should be
exercised in handling these devices as exposure to ESD may result in degradation of parametric performance.
