BUF08630 具有可调节增益 Vcom 和 1/2 AVDD 拓扑的可编程伽马电压发生器

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 150mV of either supply rail with a 10mA load. All channels are programmed using a two-wire interface that supports standard operations up to 400kHz and high-speed data transfers up to 3
