EL5126
FN7337.2
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.

(Pb-free)
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.
