Description
General part information
BUF08630 Series
The BUF08630 offers eight programmable gamma channels and one programmable VCOMchannel.
The final gamma and VCOMvalues 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.
