Texas Instruments BUF08630 Programmable Gamma-Voltage Generators

Texas Instruments BUF08630 programmable gamma-voltage generators offer eight programmable gamma channels and one programmable VCOM channel. TI BUF08630 programmable gamma-voltage generators have two separate memory banks, allowing simultaneous storage of two different gamma curves to facilitate switching between gamma curves. 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 TI BUF08630 supports up to 16 write operations to the on-chip memory.
