产品概述
Programmable Gamma-Voltage Generator 20Pin VQFN EP T/R
The BUF08630 offers eight programmable gamma channels and_one programmable VCOM channel.
The final gamma and_VCOM values can be stored in the on-chip， nonvolatile memory. To allow for programming errors or liquid crystal display (LCD) panel rework， the BUF08630 supports up to 16 write operations to the on-chip memory.
The BUF08630 has two separate memory banks， allowing simultaneous storage of two different gamma curves to facilitate switching between gamma curves.
All gamma and_VCOM channels offer a rail-to-rail output that typically swings to within 150 mV of either supply rail with a 10-mA load. All channels are programmed using a two-wire interface that supports standard operations up to 400 kHz， and_high-speed data transfers up to 3.4 MHz.
The BUF08630 is manufactured using Texas Instruments’ proprietary， state-of-the-art， high-voltage CMOS process. This process offers very dense logic and_high supply voltage operation of up to 20V. The BUF08630 is available in a 20-pin QFN package， and_is specified from –40°C to +95°C.
