  • Product introduction

Программируемый BUF08821 предлагает восемь каналов плюс один программируемый гамма-канал Wycombe.

The final Gamma and Wycombe values can be stored in on-chip, non-volatile memory.Чтобы разрешить программные ошибки или доработку ЖК-панели, BUF08821 поддерживает до 16 операций записи для памяти сэмплов.

Существует две независимые памяти BUF08821, которые позволяют одновременно хранить две разные гамма-кривые, чтобы облегчить переключение гамма-кривых.

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.
