Product Introduction

Programmable BUF22821 gamma channels, offering 22 programmable Wycombe distribution channels, two static gamma channels.It is ideal for new digital sources that require 22 gamma channels.

The final Gamma and Wycombe values can be stored on tablets, non-volatile memories.To allow program errors or LCD panel rework, BUF22821 supports up to 16 write operations and sample memory.While having two independent BUF22821 memories, two different gamma curves are allowed to be stored by the bank to facilitate switching between gamma curves.

All Gamma and Wycombe companies offer a rail-to-rail output channel within a typical 100mV swing-to-orbit 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.
