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.
A number of the EL5226 and EL5326 can be stacked for applications requiring more than 12 outputs. The reference inputs can be tied to the rails, enabling each part to output the full voltage range, or alternatively, they can be connected to external resistors to split the output range and enable finer resolutions of the outputs.
The EL5226 has 10 outputs and the EL5326 has 12 outputs and both are available in a 28-pin TSSOP package. They are specified for operation over the full -40°C to +85°C temperature range.
