Description
AI
The BUF11705 is a multi-channel buffer targeted towards gamma correction in high-resolution LCD panels. It is pin-compatible with the existing BUF11702 and BUF11704 and operates at higher supply voltages up to 22 V (24 V absolute max). The higher supply voltage enables faster response times and brighter images in large-screen LCD panels. This is especially important in LCD TV applications.
The BUF11705 offers 10 gamma channels. For additional space and cost savings, a VCOM channel with> 100 mA drive capability is integrated into the BUF11705.
The BUF11705 is available in the TSSOP-28 PowerPAD package for dramatically increased power dissipation capability. This allows a large number of channels to be handled safely in one package.
A flow-through pinout has been adopted to allow simple PCB routing and maintain cost-effectiveness. All inputs and outputs of the BUF11705 incorporate internal ESD protection circuits that prevent functional failures at voltages up to 8 kV (HBM), 2 kV (CDM), and 300 V (MM).
