10-Channel TFT-LCD Reference Voltage Generator

The EL5225 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.
