General Description
The DS3510 is a programmable gamma and VCOM volt-
age generator which supports both real-time updating
as well as multibyte storage of gamma/VCOM data in on-
chip EEPROM memory. An independent 8-bit DAC, two
8-bit data registers, and 4 bytes of EEPROM memory
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 reg-
isters 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 pads or from a fixed memory
address.
