EL5525

18-Channel TFT-LCD Reference Voltage Generator

DATASHEET

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 -40°C to

+85°C temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ special

Pb-free material sets, molding compounds/die attach materials, and 100%

matte tin plate plus anneal (e3 termination finish, which is 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.
