BUF16821中文资料具有集成双列存储器的 16 通道伽玛电压发生器和 Vcom 校准器数据手册TI规格书

描述 Description

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 3.4MHz. The BUF16821 is manufactured using Texas Instruments' proprietary, state-of-the-art, high-voltage CMOS process. This process offers very dense logic and high supply voltage operation of up to 20V. The BUF16821 is offered in a HTSSOP-28 PowerPAD™ package, and is specified from -40°C to +85°C.
