EL5325
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°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.

EL5325
To facilitate the system designs that use multiple EL5325
chips, a buffered serial output of the shift register (SDO pin)
is available. Data appears on the SDO pin at the 16th falling
SCLK edge after being applied to the SDI pin.
To control the multiple EL5325 chips from a single three-wire
serial port, just connect the ENA pins and the SCLK pins
together, connect the SDO pin to the SDI pin on the next
chip. While the ENA is held low, the 16m-bit data is loaded to
the SDI input of the first chip. The first 16-bit data will go to
the last chip and the last 16-bit data will go to the first chip.
While the ENA is held high, all addressed outputs will be
updated simultaneously.
The Serial Timing Diagram and parameters table show the
timing requirements for three-wire signals.
The serial data has a minimum length of 16 bits, the MSB
(most significant bit) is the first bit in the signal. The bits are
allocated to the following functions (also refer to the Control
Bits Logic Table)
• Bit 15 is always set to a zero
• Bit 14 controls the source of the clock, see the next
section for details
• Bits 13 through 10 select the channel to be written to,
these are binary coded with channel A = 0, and channel
H=7
• The 10-bit data is on bits 9 through 0. Some examples of
data words are shown in the table of Serial Programming
