General Description

age generator that supports both real-time updating as

chip EEPROM memory. An independent 10-bit DAC, two

10-bit data registers, and four words of EEPROM memo-

ry are provided for each individually addressable

amplifiers are integrated on-chip, providing rail-to-rail,

low-power (400µA/gamma channel) operation. The

peak) and a fast-settling buffer amplifier optimized to

interface. Interface performance and flexibility are

enhanced by a pair of independently loaded data latch-

400kHz. The multitable EEPROM memory enables a

rich variety of display system enhancements, including

support for temperature or light-level dependent

gamma tables, enabling of factory or field automated

display adjustment, and support for backlight dimming

algorithms to reduce system power. Upon power-up

and depending on mode, DAC data is selected from

EEPROM by the S0/S1 pins or from a fixed memory

address.
