EL5225

10-Channel TFT-LCD Reference Voltage

Generator

The EL5225 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 3-wire, SPI compatible interface.

A number of the EL5225 can be stacked for applications

requiring more than 10 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 EL5225 has 10 outputs, and is available in the 24-pin

TSSOP package. They are specified for operation over the

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

NOTE: Intersil Pb-free 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-020C.
