Preliminary
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
-40°C to +85°C temperature range.
