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.
