General Description
The DS3510 is a programmable gamma and VCOM voltage generator which supports both real-time updating as well as multibyte storage of gamma/VCOM data in on-chip EEPROM memory. An independent 8-bit DAC, two 8-bit data registers, and 4 bytes 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 fastsettling buffer amplifier optimized to drive the VCOM node of a wide range of TFT-LCD panels.
