EL5220C, EL5420C
General Description
The EL5420C and EL5220C are low power, high voltage, rail-to-rail
input-output amplifiers. The EL5220C contains two amplifiers in one
package, and the EL5420C contains four amplifiers. Operating on sup-
plies ranging from 5V to 15V, while consuming only 500µA per
amplifier, the EL5420C and EL5220C have a bandwidth of 12MHz --
(-3dB). They also provide common mode input ability beyond the sup-
ply rails, as well as rail-to-rail output capability. This enables these
amplifiers to offer maximum dynamic range at any supply voltage.
The EL5420C and EL5220C also feature fast slewing and settling
times, as well as a high output drive capability of 30mA (sink and
source). These features make these amplifiers ideal for use as voltage
reference buffers in Thin Film Transistor Liquid Crystal Displays
(TFT-LCD). Other applications include battery power, portable
devices, and anywhere low power consumption is important.
The EL5420C is available in a space-saving 14-pin TSSOP package,
the industry-standard 14-pin SO package, as well as a 16-pin LPP
package. The EL5220C is available in the 8-pin MSOP package. Both
feature a standard operational amplifier pin out. These amplifiers are
specified for operation over the full -40°C to +85°C temperature
range.

Applications Information
Product Description
The EL5220C and EL5420C voltage feedback amplifi-
ers 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
EL5220C and EL5420C ideal for a wide range of gen-
eral-purpose applications. Connected in voltage follower
mode and driving a load of 10k and 12pF, the
EL5220C and EL5420C have a -3dB bandwidth of
12MHz while maintaining a 10V/µs slew rate. The
EL5220C is a dual amplifier while the EL5420C is a
quad amplifier.
Operating Voltage, Input, and Output
The EL5220C and EL5420C 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
EL5220C and EL5420C specifications are stable over
both the full supply range and operating temperatures of
-40 °C to +85 °C. Parameter variations with operating
voltage and/or temperature are shown in the typical per-
formance curves.
The input common-mode voltage range of the EL5220C
and EL5420C extends 500mV beyond the supply rails.
The output swings of the EL5220C and EL5420C typi-
cally extend to within 80mV of positive 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 1 shows the input and output
waveforms for the device in the unity-gain configura-
tion. Operation is from ±5V supply with a 10kload
connected to GND. The input is a 10VP-P sinusoid. The
output voltage is approximately 9.985VP-P.
Figure 1. Operation with Rail-to-Rail Input and
Output
Short Circuit Current Limit
The EL5220C and EL5420C 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 reli-
ability is maintained if the output continuous current
never exceeds ±30 mA. This limit is set by the design of
the internal metal interconnects.
Output Phase Reversal
The EL5220C and EL5420C are immune to phase rever-
sal as long as the input voltage is limited from (VS-) ----
-0.5V to (VS+) +0.5V. Figure 2 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 over-
voltage damage could occur.

Power Dissipation
With the high-output drive capability of the EL5220C
and EL5420C amplifiers, it is possible to exceed the
125°C “absolute-maximum 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:
where:
TJMAX = Maximum Junction Temperature
TAMAX= Maximum Ambient Temperature
θJA = Thermal Resistance of the Package
PDMAX = 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 supply voltage, plus the power in the IC due to the
loads, or:
when sourcing, and:
when sinking.
where
i = 1 to 2 for Dual and 1 to 4 for Quad
VS = Total Supply Voltage
ISMAX = Maximum Supply Current Per Amplifier
VOUTi = Maximum Output Voltage of the Application
ILOADi = Load Current
If we set the two PDMAX equations equal to each other,
we can solve for RLOADi to avoid device overheat. Fig-
ures 3, 4, and 5 provide a convenient way to see if the
device will overheat. The maximum safe power dissipa-
tion can be found graphically, based on the package type
and the ambient temperature. By using the previous
equation, it is a simple matter to see if PDMAX exceeds
the device's power derating curves. To ensure proper
operation, it is important to observe the recommended
derating curves in Figures 3, 4, and 5.

Unused Amplifiers
It is recommended that any unused amplifiers in a dual
and a quad package be configured as a unity gain fol-
lower. The inverting input should be directly connected
to the output and the non-inverting input tied to the
ground plane.
Driving Capacitive Loads
The EL5220C and EL5420C can drive a wide range of
capacitive loads. As load capacitance increases, how-
ever, the -3dB bandwidth of the device will decrease and
the peaking increase. The amplifiers drive 10pF loads in
parallel with 10k 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 5 and 50) can be placed in series with the
output. However, this will obviously reduce the gain
slightly. 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 150 and 10nF are typical. The advantage of a snub-
ber is that it does not draw any DC load current or
reduce the gain
Power Supply Bypassing and Printed Circuit
Board Layout
The EL5220C and EL5420C can provide gain at high
frequency. As with any high-frequency device, good
printed circuit board layout is necessary for optimum
performance. Ground plane construction is highly rec-
ommended, 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 ceramic 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 capacitor 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.
