Description: I²C Gamma And VCOM Buffer With EEPROM
The DS3514 is a programmable gamma and VCOM voltage 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 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 (400µA/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. |
