The BUF16821 offers 16 programmable gamma channels and two programmable VCOM channels.

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 BUF16821 supports up to 16 write operations to the on-chip memory.

The BUF16821 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 an I2C interface that supports standard operations up to 400kHz and high-speed data transfers up to 3.
