EL5126

8-Channel TFT-LCD Reference Voltage

Generator

The EL5126 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 number of the EL5126 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 EL5126 has 8 outputs and is available in a 32 Ld QFN

package. It is specified for operation over the full -40°C to

+85°C temperature range.

Features

• 8-channel reference outputs

• Accuracy of ±0.1%

• Supply voltage of 4.5V to 16.5V

• Digital supply 3.3V to 5V

• Low supply current of 10mA

• Rail-to-rail capability

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.
