The EL5225 is designed to produce the reference voltagesrequired in TFT-LCD applications. Each output isprogrammed to the required voltage with 10 bits ofresolution. Reference pins determine the high and lowvoltages of the output range, which are capable of swingingto either supply rail. Programming of each output isperformed using the 3-wire, SPI compatible interface.A number of the EL5225 can be stacked for applicationsrequiring more than 10 outputs. The reference inputs can betied to the rails, enabling each part to output the full voltagerange, or alternatively, they can be connected to externalresistors to split the output range and enable finerresolutions of the outputs.The EL5225 has 10 outputs, and is available in the 24-pinTSSOP package. They are specified for operation over thefull -40°C to +85°C temperature range.
