BUF16821 16 channels are available, both sets of programmable gamma wickom channels.
The final Gamma and Wycombe values can be stored in on-chip, non-volatile memory.To allow program errors or LCD panel rework, the BUF16821 supports up to 16 write operations for sample memory.
There are two independent BUF16821 memories that allow two different gamma curves to be stored simultaneously to facilitate switching of gamma curves.
All Gamma and Wycombe companies offer a rail-to-rail output channel within a typical 150mV swing to orbit with one condition: either supply the load.All channels are programmed using the I2C interface for standard operation, supporting and high-speed data transmission up to 400kHz 3.
