10- and 12-Channel TFT-LCD Reference Voltage Generators
FN7118 Rev 3.00 May 9, 2005
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.
Features
10- to 12-channel reference outputs Accuracy of ±1% Supply voltage of 5V to 16.5V Digital supply 3.3V to 5V Low supply current of 10mA Rail-to-rail capability Pb-Free available (RoHS compliant)
Applications
TFT-LCD drive circuits Reference voltage generators
