BUF08630中文资料具有可调增益 Vcom 和 1/2 AVDD 拓扑的 8 通道伽马电压发生器数据手册TI规格书

描述 Description

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.
