I2C Gamma And VCOM Buffer With EEPROM

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. By Maxim Integrated Products
