Data Sheet
10-Channel TFT-LCD Reference Voltage
Generator
The EL5225 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 the EL5225 can be stacked for applications
requiring more than 10 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 EL5225 has 10 outputs, and is available in the 24-pin
TSSOP package. They are specified for operation over the
full -40°C to +85°C temperature range.

General Description
The EL5225 provides a versatile method of providing the
reference voltages that are used in setting the transfer
characteristics of LCD display panels. The V/T
(Voltage/Transmission) curve of the LCD panel requires that
a correction is applied to make it linear; however, if the panel
is to be used in more than one application, the final curve
may differ for different applications. By using the EL5225,
the V/T curve can be changed to optimize its characteristics
according to the required application of the display product.
Each of the eight reference voltage outputs can be set with a
10-bit resolution. These outputs can be driven to within
50mV of the power rails of the EL5225. As all of the output
buffers are identical, it is also possible to use the EL5225 for
applications other than LCDs where multiple voltage
references are required that can be set to 10 bit accuracy.
5
Digital Interface
The EL5225 uses a simple 3-wire SPI compliant digital
interface to program the outputs. The EL5225 can support
the clock rate up to 5MHz.
Serial Interface
The EL5225 is programmed through a three-wire serial
interface. The start and stop conditions are defined by the
ENA signal. While the ENA is low, the data on the SDI (serial
data input) pin is shifted into the 16-bit shift register on the
positive edge of the SCLK (serial clock) signal. The MSB (bit
15) is loaded first and the LSB (bit 0) is loaded last (see
Table 1). After the full 16-bit data has been loaded, the ENA
is pulled high and the addressed output channel is updated.
The SCLK is disabled internally when the ENA is high. The
SCLK must be low before the ENA is pulled low.
FN7356.0
March 11, 2004
EL5225
To facilitate the system designs that use multiple EL5225
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.
TABLE 1. CONTROL BITS LOGIC TABLE
To control the multiple EL5225 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

CLOCK OSCILLATOR
TRANSFER FUNCTION
The EL5225 requires an internal clock or external clock to
refresh its outputs. The outputs are refreshed at the falling OSC
clock edges. The output refreshed switches open at the rising
edges of the OSC clock. The driving load shouldn’t be changed
at the rising edges of the OSC clock. Otherwise, it will generate
a voltage error at the outputs. This clock may be input or output
via the clock pin labeled OSC. The internal clock is provided by
an internal oscillator running at approximately 21kHz and can
be output to the OSC pin. In a 2 chip system, if the driving loads
are stable, one chip may be programmed to use the internal
oscillator; then the OSC pin will output the clock from the
internal oscillator. The second chip may have the OSC pin
connected to this clock source.
The transfer function is:
data
V OUT ( IDEAL ) = V REFL + ------------- × ( V REFH - V REFL )
1024
where data is the decimal value of the 10-bit data binary
input code.
The output voltages from the EL5225 will be derived from
the reference voltages present at the VREFL and VREFH
pins. The impedance between those two pins is about 32kΩ.
Care should be taken that the system design holds these two
reference voltages within the limits of the power rails of the
EL5225. GND < VREFH ≤ VS and GND ≤ VREFL ≤ VREFH.
In some LCD applications that require more than 10
channels, the system can be designed such that one
EL5225 will provide the Gamma correction voltages that are
more positive than the VCOM potential. The second EL5225
can provide the Gamma correction voltage more negative
than the VCOM potential. The Application Drawing shows a
system connected in this way.
7
For transient load application, the external clock Mode
should be used to ensure all functions are synchronized
together. The positive edge of the external clock to the OSC
pin should be timed to avoid the transient load effect. The
Application Drawing shows the LCD H rate signal used, here
the positive clock edge is timed to avoid the transient load of
the column driver circuits.
After power on, the chip will start with the internal oscillator
mode. At this time, the OSC pin will be in a high impedance
condition to prevent contention. By setting B14 to high, the
chip is on external clock mode. Setting B14 to low, the chip is
on internal clock mode.

CHANNEL OUTPUTS
Each of the channel outputs has a rail-to-rail buffer. This
enables all channels to have the capability to drive to within
50mV of the power rails, (see Electrical Characteristics for
details).
When driving large capacitive loads, a series resistor should
be placed in series with the output. (Usually between 5Ω and
50Ω).
Each of the channels is updated on a continuous cycle, the
time for the new data to appear at a specific output will
depend on the exact timing relationship of the incoming data
to this cycle.
The best-case scenario is when the data has just been
captured and then passed on to the output stage
immediately; this can be as short as 48µs. In the worst-case
scenario, this will be 480µs when the data has just missed
the cycle.
When a large change in output voltage is required, the
change will occur in 2V steps, thus the requisite number of
timing cycles will be added to the overall update time. This
means that a large change of 16V can take between 3.8ms

The output voltage is generated from the DAC, which is VIN
at the above circuit. The refreshed switches are controlled
by the internal or external oscillator signal. When the OSC
clock signal is low, the switch S1 and S2 are closed. The
output VOUT = VIN and at the same time the sample and
hold cap CH is being charged. When the OSC clock signal is
high, the refreshed switch S1 and S2 are opened and the
output voltage is maintained by CH. This refreshed process
FN7356.0
March 11, 2004
EL5225
will repeat every 10-clock cycles for each channel. The time
takes to update the output depends on the timing at the VIN
and the state of the switches. It can take 1 to 10 clock cycles
to update each output.
VOUT1
For the sample and hold capacitor CH to maintain the
correct output voltage, the driving load shouldn’t be changed
at the rising edge of the OSC signal. Since at the rising edge
of the OSC clock, the refreshed switches are being opened,
if the load changes at that time, it will generate an error
output voltage. For a fixed load condition, the internal
oscillator can be used.
For the transient load condition, the external OSC mode
should be used to avoid the conflict between the rising edge
of the OSC signal and the changing load. So a timing delay
circuit will be needed to delay the OSC signal and avoid the
rising edge of the OSC signal and changing the load at the
same time.

At the falling edge of the OSC, output 1 is refreshing and one
clock cycle later, output2 is being refreshed. The spike you
see here is the response of the output amplifier when the
refreshed switches are closed. When driving a big capacitor
load, there will be ringing at the spikes because the phase
margin of the amplifier is decreased.

Here, the OSC signal is synchronized to the load signal. The
rising edge of the OSC signal is then delayed by some
amount of time and gives enough time for CH to be charged
to a new voltage before the switches are opened.
The speed of the external OSC signal shouldn’t be greater
than 70kHz because for the worst condition, it will take at
least 4µs to charge the sample and hold Capacitor CH. The
pulse width has to be at least 4µs long. From our lab test, the
duty cycle of the OSC signal must be greater than 30%.
POWER DISSIPATION
With the 30mA maximum continues output drive capability
for each channel, it is possible to exceed the 125°C absolute
maximum junction temperature. Therefore, it is important to
calculate the maximum junction temperature for the
application to determine if load conditions need to be
modified for the part to remain in the safe operation.
The maximum power dissipation allowed in a package is
determined according to:
T JMAX - T AMAX
P DMAX = --------------------------------------------Θ JA
where:
• TJMAX = Maximum junction temperature
• TAMAX = Maximum ambient temperature
• θJA = Thermal resistance of the package
• PDMAX = Maximum power dissipation in the package
9
FN7356.0
March 11, 2004
EL5225
The maximum power dissipation actually produced by the IC
is the total quiescent supply current times the total power
supply voltage and plus the power in the IC due to the loads.
POWER SUPPLY BYPASSING AND PRINTED CIRCUIT
BOARD LAYOUT
Where:
Good printed circuit board layout is necessary for optimum
performance. A low impedance and clean analog ground
plane should be used for the EL5225. The traces from the
two ground pins to the ground plane must be very short.
Lead length should be as short as possible and all power
supply pins must be well bypassed. A 0.1µF ceramic
capacitor must be place very close to the VS, VREFH,
VREFL, and CAP pins. A 4.7µF local bypass tantalum
capacitor should be placed to the VS, VREFH, and VREFL
pins.
• i = 1 to total 10
APPLICATION USING THE EL5225
• VS = Supply voltage
In the first application drawing, the schematic shows the
interconnect of a pair of EL5225 chips connected to give
10 gamma corrected voltages above the VCOM voltage, and
10 gamma corrected voltages below the VCOM voltage.
P DMAX = V S × I S + Σ [ ( V S - V OUT i ) × I LOAD i ]
when sourcing, and:
P DMAX = V S × I S + Σ ( V OUT i × I LOAD i )
when sinking.
• IS = Quiescent current
• VOUTi = Output voltage of the i channel
• ILOADi = Load current of the i channel
