Gamma Correction Channels: 6, 4  
Integrated V Buffer  
The BUFxx703 are a series of multi-channel buffers  
targeted towards gamma correction in high-resolution  
liquid crystal display (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.

Excellent Output Current Drive:  
– Gamma Channels: > 10mA

Large Capacitive Load Drive Capability  
Rail-to-Rail Output  
For additional space and cost savings, a V  
channel  
COM  
with higher current drive capability is integrated in the  
BUF07703 and BUF05703.  
PowerPAD Package: BUF07703  
Low-Power/Channel: < 250µA  
Wide Supply Range: 4.5V to 16V  
Specified for 0°C to 85°C  
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 BUFxx703  
incorporate internal ESD protection circuits that prevent  
functional failures at voltages up to 4kV HBM and 1.5kV  
CDM.  
High ESD Rating: 4kV HBM, 1.5kV CDM  
APPLICATIONS

LCD Television Displays  
The various buffers within the BUFxx703 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

The BUF07703 is available in the HTSSOP  
PowerPAD package for dramatically increased power  
dissipation capability. The BUF06703 and BUF05703  
are available in standard TSSOP-16 and TSSOP-14  
packages.
