General Description

Features

The DS3514 is a programmable gamma and V

volt-

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.
