Features, Applications

FEATURES D Gamma Correction Channels: 6 D Integrated VCOM Buffer D Excellent Output Current Drive:

The BUFxx702 are a series of multi-channel buffers targeted towards gamma correction in high-resolution LCD panels. The number of gamma correction channels required depends on a variety of factors and differs greatly from design to design. Therefore, various channel options are offered. For additional space and cost savings, a VCOM channel with higher current drive capability is integrated in the BUF11702 and BUF07702. The various buffers within the BUFxx702 are carefully matched to the voltage I/O requirements for the gamma correction application. Each buffer is capable of driving heavy capacitive loads and offers fast load current switching. The VCOM channel has increased output drive > 100mA and can handle even larger capacitive loads. The BUF07702, as well as the BUF11702, are available in the TSSOP-PowerPAD package for dramatically increased power dissipation capability. This way, a large number of channels can be handled safely in one package. A flow-through pin out has been adopted to allow simple PCB routing and maintain the cost effectiveness of this solution. All inputs and outputs of the BUFxx702 incorporate internal ESD protection circuits that prevent functional failures at voltages to 4kV (HBM) as tested under MIL-STD-883C Method 3015.
