BUF12840AIRGER

The BUF12840 offers 12 programmable gamma channels with external electrically erasable programmable read-only memory (EEPROM) read capabilities.The BUF12840 has two separate memory banks that allow simultaneous storage of two different gamma curves to facilitate switching between gamma curves. All gamma channels offer a rail-to-rail output that typically swings to within 200mV of either supply rail with a 5mA 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 BUF12840 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 BUF12840 is offered in a QFN-24 package, and is specified from –40°C to +95°C.
