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-pin
TSSOP package. They are specified for operation over the
full -40°C to +85°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.
