General Description
The DS3508 is a programmable 8-channel gamma volt-
age generator with one byte of on-chip EEPROM and
one byte of SRAM memory per channel. Each channel
is composed of an independent 8-bit DAC with an asso-
ciated EEPROM/SRAM pair. At power-up, nonvolatile
(NV) EEPROM gamma data is loaded into its corre-
sponding SRAM register that drives the associated 8-bit
DAC. An on-chip control register allows selectable con-
trol of writing to SRAM/EEPROM or SRAM only.
The DS3508 is designed for low-power operation and
draws less than 2mA (typ) from the VDD supply.
Programming occurs through an I2C-compatible serial
interface with support for speeds up to 400kHz.
