It is ideal for the new – 2-CHANNEL STATIC GAMMA 10-bit source drivers that require 22 gamma • 2-CHANNEL PROGRAMMABLE V COM channels. • 10-BIT RESOLUTION The final gamma and VCOM values can be stored in • 16x REWRITABLE NONVOLATILE MEMORY the on-chip, nonvolatile memory. To allow for programming errors or liquid crystal display (LCD) • TWO INDEPENDENT MEMORY BANKS panel rework, the BUF22821 supports up to 16 write • RAIL-TO-RAIL OUTPUT operations to the on-chip memory. The BUF22821 • LOW SUPPLY CURRENT: 0.5mA/channel has two separate banks of memory, allowing • SUPPLY VOLTAGE: 9V to 20V simultaneous storage of two different gamma curves to facilitate switching between gamma curves. • DIGITAL SUPPLY: 2V to 5.5V All gamma and VCOM channels offer a rail-to-rail • I2C™ INTERFACE output that typically swings to within 100mV of either supply rail with a 10mA load. All channels are programmed using an I2C interface that supports • TFT-LCD REFERENCE DRIVERS standard operations up to 400kHz and high-speed data transfers up to 3.4MHz. The BUF22821 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 BUF22821 is offered in a HTSSOP-38 PowerPAD™ package. It is specified from –40 °C to +85°C.
