DS3508 I²C, 8-Channel Gamma Buffer with EEPROM

Description

The DS3508 is a programmable 8-channel gamma voltage 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 associated EEPROM/SRAM pair. At power-up, nonvolatile (NV) EEPROM gamma data is loaded into its corresponding SRAM register that drives the associated 8-bit DAC. An on-chip control register allows selectable control of writing to SRAM/EEPROM or SRAM only.

The DS3508 is designed for low-power operation and draws less than 2mA (typ) from the V_DD supply. Programming occurs through an I²C-compatible serial interface with support for speeds up to 400kHz.
