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.

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:
PDMAX
=
T----J---M-----A-----X------–----T----A-----M-----A-----X--
ΘJA
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:
PDMAX = Σi × [VS × ISMAX + (VS+ – VOUTi ) × ILOADi]
when sourcing, and:
PDMAX = Σi × [VS × ISMAX + (VOUTi – VS- ) × ILOADi]
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.
