EL5120, EL5220, EL5420
12MHz Rail-to-Rail Input-Output Op Amps
The EL5120, EL5220, and EL5420 are low power, high
voltage, rail-to-rail input-output amplifiers. The EL5120
contains a single amplifier, the EL5220 contains two
amplifiers, and the EL5420 contains four amplifiers.
Operating on supplies ranging from 5V to 15V, while
consuming only 500µA per amplifier, the EL5120, EL5220,
and EL5420 have a bandwidth of 12MHz (-3dB). They also
provide common mode input ability beyond the supply rails,
as well as rail-to-rail output capability. This enables these
amplifiers to offer maximum dynamic range at any supply
voltage.
The EL5120, EL5220, and EL5420 also feature fast slewing
and settling times, as well as a high output drive capability of
30mA (sink and source). These features ma ke thes e
amplifiers ideal for use as voltage reference buffers in Thin
Film T ransistor Liquid Crystal Displays (TFT-LCD). Other
applications include battery po wer, portab le devices, and
anywhere low power consumption is important.
The EL5420 is available in the space-saving 14 Ld TSSOP
package, the industry-standard 14 Ld SOIC package, as well
as the 16 Ld QFN package. The EL5220 is available in the
8 Ld MSOP package and the 8Ld DFN package. The
EL5120 is available in the 5 Ld TSOT package. All feature a
standard operational amplifier pin out. These amplifiers are
specified for operation with an ambient and junction
temperature range of -40°C to +125°C.

Applications Information
Product Descr iption
The EL5120, EL5220, and EL5420 voltage feedback
amplifiers are fabricated using a high voltage CMOS
process. They exhibit rail-to-rail input and output capability,
they are unity gain stable, and have low power consumption
(500µA per amplifier). These features make the EL5120,
EL5220, and EL5420 ideal for a wide range of general-
purpose applications. Connected in voltage follower mode
and driving a load of 10kΩ and 12pF, the EL5120, EL5220,
and EL5420 have a -3dB bandwidth of 12MHz while
maint a i nin g a 1 0V/µs slew rate. The EL5120 is a single
amplifier , the EL5220 is a dual amplifier , and the EL5420 is a
quad amplifier.
Operating Voltage, Input, and Output
The EL5120, EL5220, and EL5420 are specified with a
single nominal supply voltage from 5V to 15V or a split
supply with its total range from 5V to 15V. Correct operation
is guaranteed for a supply range of 4.5V to 16.5V. Most
EL5120, EL5220, and EL5420 specifications are stable over
both the full supply range and operating junction
temperature range of -40°C to +125°C. Parameter variations
with operating voltage and/or temperature are shown in the
typical performance curves.
The input common-mode voltage range of the EL5120,
EL5220, and EL5420 extends 500mV beyond the supply
rails. The output swings of the EL5120, EL5220, and
EL5420 typically extend to within 80mV of po sitive and
negative supply rails with load currents of 5mA. Decreasing
load currents will extend the output voltage range even
closer to the supply rails. Figure 25 shows the input and
output waveforms for the device in the unity-gain
configuration. Operation is from ±5V supply with a 10kΩ load
connected to GND. The input is a 10VP-P sinusoid. The
output voltage is approximately 9.985VP-P.
FIGURE 25. OPERATION WITH RAIL-TO-RAIL INPUT AND
OUTPUT
Short Circuit Current Limit
The EL5120, EL5220, and EL5420 will limit the short circuit
current to ±120mA if the output is directly shorted to the
positive or the negative supply. If an output is shorted
indefinitely, the power dissipation could easily increase such
that the device may be damaged. Maximum reliability is
maintained if the output continuous current never exceeds
±30mA. This limit is set by the design of the internal metal
interconnects.
Output Phase Reversal
The EL5120, EL5220, and EL5420 are immune to phase
reversal as long as the input voltage is limited from (VS-)
-0.5V to (VS+) +0.5V. Figure 26 shows a photo of the output
of the device with the input voltage driven beyond the supply
rails. Although the device's output will not change phase, the
input's overvoltage should be avoided. If an input voltage
exceeds supply voltage by more than 0.6V, electrostatic
protection diodes placed in the input stage of the device
begin to conduct and overvoltage damage coul d occur.
FIGURE 26. OPERATION WITH BEYOND-THE-RAILS INPUT
Power Dissipation
With the high-output drive capability of the EL5120, EL5220,
and EL5420 amplifiers, it is possible to exceed the +125°C
maximum operating junction temperature under certain load
current conditions. Therefore, it is important to calculate the
maximum junction temperature for the application to
determine if load conditions need to be modified for the
amplifier to remain in the safe operating area.
The maximum power dissipation allowed in a package is
determined according to Equation 1:
where:
•T
JMAX = Maximum junction temperature
•T
AMAX = Maximum ambient temper at ure
θJA = Thermal resistance of the package
•P
DMAX = Maximum power dissipation in the package
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power

shown in Equation 2:

when sinking.
where:

•V
S = Total supply voltage
•I
SMAX = Maximum supply current per amplifier
•V
OUTi = Maximum output vo ltage of the appl ication
•I
LOADi = Load current
If we set the two PDMAX equations equal to each o ther, we
can solve for RLOADi to avoid device overheat. Fig ure 27
provide a convenient way to see if the device will overheat.
The maximum safe power dissipatio n can be found
graphically, based on the package type and the ambie nt
temperature. By using the previous equation, it is a simple
matter to see if PDMAX exceeds the device's power de rati ng
curves. To ensure prop er operation, it is important to observe
the recommended derating curves in Figu re 27.
Unused Amplifiers
It is recommended that any unused amplifiers in a dual and
a quad package be configured as a unity gain follower. The
inverting input should be directly connected to the output
and the non-inverting input tied to the ground plane.
Driving Capacitive Loads
The EL5120, EL5220, and EL5420 can drive a wide range of
capacitive loads. As load capacitance increases, however,
the -3dB bandwidth of the device will decrease and the
peaking will increase. The ampli fiers drive 10pF loads in
parallel with 10kΩ with just 1.5dB of peaking, and 100pF
with 6.4dB of peaking. If less peaking is desired in these
applications, a small series resistor (usually between 5Ω and
50Ω) can be placed in series with the output. However, this
will obviously reduce the gain sligh tl y. Another method of
reducing peaking is to add a “snubber” circuit at the output.
A snubber is a shunt load consisting of a resistor in series
with a capacitor. Values of 150Ω and 10nF are typical. The
advantage of a snubber is that it does not draw any DC load
current or reduce the gain
Power Supply Bypassing and Printed Circuit
Board Layout
The EL5120, EL5220, and EL5420 can provide gain at high
frequency. As with any high-frequency device, go od printed
circuit board layout is necessary for optimum performance.
Ground plane construction is highly recommended, lead
lengths should be as short as possible and the power supply
pins must be well bypassed to reduce the risk of oscillation.
For normal single supply operation, where the VS- pin is
connected to ground, a 0.1µF ce ramic capacitor should be
placed from VS+ to pin to VS- pin. A 4.7µF tantalum
capacitor should then be connected in parallel, placed in the
region of the amplifier . One 4.7µF cap acitor may be used for
multiple devices. This same capacitor combination should be
placed at each supply pin to ground if split supplies are to be
used.
