ANX7911数据手册HYSiC中文资料规格书

描述 Description

The ANX7911 outputs 14 voltage references for Gamma correction in TFT-LCD displays and one voltage reference for Vcom. Each reference

voltage whether for Gamma or Vcom has its own 10-bit digital-to-analog converter (DAC) and

amplifier to ensure a stable voltage when critical levels and patterns are displayed.

     The ANX7911 also has integrated multiple-time programmable (MTP) memory to store Gamma and Vcom values on the chip, eliminating the need for external EEPROM. ANX7911 supports up to 1000 write operations to the on-chip non-volatile memory.

     The Gamma outputs can settle within 1us. The Vcom output can provide 100mA peak transient current and also settles within 1us. The analog supply voltage range extends from 6.5V to 18V, and the digital supply voltage range extends from 2.7V to 3.6V.

     Gamma values and the Vcom value are programmed into registers through the I2C interface.

     The ANX7911 is available in a thin 32-pin 5x5 mm WQFN green package.
