Description

The EL5525 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 EL5525 can be stacked for applications requiring more than 18 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 EL5525 has 18 outputs and comes in a 38-pin HTSSOP package. It is specified for operation over the full -40oC to +85oC temperature range.
