EL5825C - Preliminary
8-Channel TFT-LCD Reference Voltage Generator
Features
* * * * * * 8-channel reference outputs Accuracy of 0.1% Supply voltage of 5V to 16V Digital supply 3.3V to 5V Low supply current of 10mA Rail-to-rail capability
General Description
The EL5825C 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 serial interface. A serial out pin enables daisy chaining of multiple devices. A number of the EL5825C can be stacked for applications requiring more than 8 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 EL5825C has 8 outputs and is available in both the 24-pin TSSOP and the 24-pin LPP packages. It is specified for operation over the full -40C to +85C temperature range.
Applications
* TFT-LCD drive circuits * Reference voltage generators
