1FEATURES DESCRIPTION
23• Gamma Correction Channels:6,4 The BUFxx703 area seriesof multi-channel buffers
targeted towards gamma correctionin high-resolution
• Integrated VCOM Bufferliquid crystal display (LCD) panels. The numberof
• Excellent Output Current Drive: gamma correction channels required depends ona
– Gamma Channels:> 10mA varietyof factors and differs greatly from designto
VCOM:> 100mA typ design. Therefore, various channel options are
offered. For additional space and cost savings,a
• Large Capacitive Load Drive Capability VCOM channel with higher current drive capabilityis
• Rail-to-Rail Output integratedin the BUF07703 and BUF05703.
PowerPAD™ Package: BUF07703 A flow-through pinout has been adopted to allow
• Low-Power/Channel:< 250µA simple printed circuit board (PCB) routing and
Wide Supply Range: 4.5Vto 16V maintain the cost-effectiveness of this solution. All
inputs and outputs of the BUFxx703 incorporate
• Specified for –40°Cto 85°C internal ESD protection circuits that prevent functional
• High ESD Rating: 4kV HBM, 1.5kV CDM failuresat voltagesupto 4kV HBM and 1.5kV CDM.
The various buffers within the BUFxx703 are carefully
APPLICATIONS matched to the voltage I/O requirements for the
• LCD Flat Panel Displays gamma correction application. Each bufferis capable
• LCD Television Displays of driving heavy capacitive loads and offers fast load
current switching. The VCOM channel has increased
DEVICE COMPARISON output driveof> 100mA and can handle even larger capacitive loads. The BUF07703 is available in the HTSSOP PowerPAD™ package for dramatically increased power dissipation capability. The BUF06703 and BUF05703 are availablein standard TSSOP-16 and
TSSOP-14 packages.
