® EL5525 Data Sheet August 1, 2005 FN7393.1 PRELIMINARY 18-Channel TFT-LCD Reference Voltage Generator The EL5525 is 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 serial interface.

A serial out pin enables daisy c
