Product Introduction

Offerings BUF16821 16 channels, two sets of programmable Gamma Wycombe channels.

The final Gamma and Wycombe values can be stored on tablets, non-volatile memories.To allow program errors or LCD panel rework, BUF16821 supports up to 16 write operations and sample memory.

There are two independent BUF16821 memories that allow two different gamma curves to be stored simultaneously to facilitate switching between gamma curves.

All Gamma and Wycombe companies offer a rail-to-rail output channel within a typical 150mV swing-to-rail with one condition: either supply the load.All channels are programmed with an I2C interface for standard operation, supporting and high-speed data transmission up to 400kHz3.
