General Description
The DS3514 is a programmable gamma and VCOM volt-
age generator that supports both real-time updating as
well as multibyte storage of gamma/VCOM data in on-
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
gamma or VCOM channel. High-performance buffer
amplifiers are integrated on-chip, providing rail-to-rail,
low-power (400A/gamma channel) operation. The
VCOM channel features a high current drive (> 250mA
peak) and a fast-settling buffer amplifier optimized to
drive the VCOM node of a wide range of TFT-LCD panels.
Programming occurs through an I2C-compatible serial
interface. Interface performance and flexibility are
enhanced by a pair of independently loaded data latch-
es per channel, as well as support for I2C speeds up to
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.
