8-Channel TFT-LCD Reference Voltage
Generator
Features
• 8-channel reference outputs
The EL5825 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.
• Accuracy of ±0.1%
• Supply voltage of 4.5V to 16.5V
• Digital supply 3.3V to 5V
• Low supply current of 8mA
• Rail-to-rail capability
• Pb-Free plus anneal available (RoHS compliant)
A number of the EL5825 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.
Applications
• TFT-LCD drive circuits
• Reference voltage generators

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
