DS3514

The DS3514 is designed as one kind of programmable gamma and VCOM voltage generator device that can be used in (1)TFT-LCD Gamma and VCOM Buffer; (2)Adaptive Gamma and VCOM Adjustment (Real Time by I2C, Select EEPROM Through I2C or S0/S1 Pins); (3)Industrial Process Control applications. And this device 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.

Features of the DS3514 are:(1)10-Bit Gamma Buffers, 14 Channels; (2)8-Bit VCOM Buffer, 1 Channel; (3)Four 10-Bit EEPROM Words per Channel; (4)Low-Power 400 uA/ch Gamma Buffers; (5)I2C-Compatible Serial Interface; (6)Flexible Control from I2C or Pins; (7)9.0V to 15.0V Analog Supply; (8)2.7V to 5.5V Digital Supply; (9)48-Pin TQFN Package (7mm x 7mm).

The absolute maximum ratings of the DS3514 can be summarized as:(1)Soldering Temperature: Refer to the IPC/JEDEC J-STD-020 Specification;(2)Storage Temperature Range: -55°C to +125°C;(3)Programming Temperature Range: 0°C to +85°C;(4)Operating Temperature Range: -45°C to +95°C;(5)Junction Temperature: +125°C;(6)Voltage Range on SDA, SCL, A0, LD, S0, S1 Relative to GND: -0.5V to (VCC + 0.5V), not to exceed 6V;(7)Voltage Range on VDD Relative to GND: -0.5V to +16V.
