EL5325A
FN7447.1
12-Channel TFT-LCD Reference Voltage
Generator with External Shutdown
The EL5325A with external shutdown 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 EL5325A 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 EL5325A has 12 outputs and is available in a 28 Ld
TSSOP package. They are specified for operation over the
full -40°C to +85°C temperature range.

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.
