DATASHEET EL5226, EL5326 10- and 12-Channel TFT-LCD Reference Voltage Generators FN7118 Rev 3.00 May 9, 2005 The EL5226 and EL5326 are designed to produce the reference voltages required in TFT-LCD applications.

Each output is programmed to the required voltage with 10 bits of resolution.

Reference pins determine the high and low voltages of the output range, which are capable of swinging to either supply rail.

Programming of each output is performed using the I2C serial interface.
