® EL5325 Data Sheet March 5, 2004 FN7437.1 12-Channel TFT-LCD Reference Voltage Generator The EL5325 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 3-wire, SPI compatible interface.
