EL5412
FN7394.1
40MHz Rail-to-Rail Input-Output Op Amp
The EL5412 is a low power, high voltage rail-to-rail input-
output amplifier containing four amplifiers in one package.
Operating on supplies ranging from 5V to 15V, while
consuming only 2.5mA per amplifier, the EL5412 has a
bandwidth of 40MHz (-3dB). It also provides common mode
input ability beyond the supply rails, as well as rail-to-rail
output capability. This enables this amplifier to offer
maximum dynamic range at any supply voltage.
The EL5412 also features fast slewing and settling times, as
well as a high output drive capability of 65mA (sink and
source), continuous current, and ±190mA short-circuit
current. These features make this amplifier ideal for high
speed filtering and signal conditioning and VCOM driving
applications. Other applications include battery-powered and
portable devices and anywhere low power consumption is
important.
The EL5412 is available in both the 14-pin TSSOP and 14-
pin HTSSOP packages and features a standard operational
amplifier pinout. They are specified for operation over the full
-40°C to +85°C temperature range.

EL5412
Applications Information
Product Description
The EL5412 voltage feedback amplifier is fabricated using a
high voltage CMOS process. It exhibits rail-to-rail input and
output capability, is unity gain stable and has low power
consumption (2.5mA per amplifier). These features make
the EL5412 ideal for a wide range of general-purpose
applications. Connected in voltage follower mode and driving
a load of 2k, the EL5412 has a -3dB bandwidth of 40MHz
while maintaining a 55V/µs slew rate. The EL5412 is a quad
amplifier.
Operating Voltage, Input, and Output
The EL5412 is 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 EL5412 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 performance
curves.
The input common-mode voltage range of the EL5412
extends 500mV beyond the supply rails. The output swings
of the EL5412 typically extend to within 100mV 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 8 shows the
input and output waveforms for the device in the unity-gain
configuration. Operation is from ±5V supply with a 1kload
connected to GND. The input is a 10VP-P sinusoid. The
output voltage is approximately 9.8VP-P.

FIGURE 8. OPERATION WITH RAIL-TO-RAIL INPUT AND
OUTPUT
Output Current Driving Capability
The EL5412 will limit the short-circuit current to ±190mA 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 ±65mA. This limit is set by
the design of the internal metal interconnects.
Output Phase Reversal
The EL5412 is immune to phase reversal as long as the
input voltage is limited from VS- -0.5V to VS+ +0.5V. Figure 9
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 could occur.

FIGURE 9. OPERATION WITH BEYOND-THE-RAILS INPUT
Power Dissipation
With the high-output drive capability of the EL5412 amplifier,
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.
