Maxim Integrated DS3508

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. The DS3508 is designed for low-power operation and draws less than 2mA (typ) from the V DD supply.

GENERAL DESCRIPTION

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. Programming occurs through an I2C-compatible serial interface with support for speeds up to 400kHz. o 8-Bit Gamma DACs, 8 Channels o 1 Byte EEPROM and 1 Byte SRAM per Channel o Ultra-Low Power (2mA IDD, typ) o 400kbps I2C Interface o 9.0V to 15.5V Analog Supply o 2.7V to 5.5V Digital Supply o 20-Pin TSSOP Package o Address Pin Allows Two DS3508s to Reside on the Same I2C Bus
