FN7437.1
12-Channel TFT-LCD Reference Voltage
Generator
The EL5325 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 EL5325 can be stacked for applications
requiring more than 12 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 EL5325 has 12 outputs and is available in a 28-pin
TSSOP package. They are specified for operation over the
full -40掳C to +85掳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 is 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-020B.
