The BUF08832 offers eight programmable gamma channels and one programmable VCOM channel.

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 BUF08832 supports up to 16 write operations to the on-chip memory.

The BUF08832 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 a Two-Wire interface that supports standard operations up to 400kHz and high-speed data transfers up to 3.4MHz.

The BUF08832 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 BUF08832 is offered in a HTSSOP-20 PowerPAD package, and is specified from –40°C to +85°C.
