Applications Information
Product Description
The EL5210 and EL5410 voltage feedback amplifiers are
fabricated using a high voltage CMOS process. They exhibit
Rail-to-Rail input and output capability, are unity gain stable
and have low power consumption (2.5mA per amplifier).
These features make the EL5210 and EL5410 ideal for a
wide range of general-purpose applications. Connected in
voltage follower mode and driving a load of 1k
Ω and 12pF,
the EL5210 and EL5410 have a -3dB bandwidth of 30MHz
while maintaining a 33V/S slew rate. The EL5210 is a dual
amplifier while the EL5410 is a quad amplifier.
Operating Voltage, Input, and Output
The EL5210 and EL5410 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 EL5210 and EL5410
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 EL5210 and
EL5410 extends 500mV beyond the supply rails. The output
swings of the EL5210 and EL5410 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 1
shows the input and output waveforms for the device in the
unity-gain configuration. Operation is from ±5V supply with a
1k
Ω load connected to GND. The input is a 10V
P-P sinusoid.
The output voltage is approximately 9.8VP-P.
FIGURE 1. OPERATION WITH RAIL-TO-RAIL INPUT AND
OUTPUT
Short Circuit Current Limit
The EL5210 and EL5410 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 EL5210 and EL5410 are immune to phase reversal 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 overvoltage damage could occur.
FIGURE 2. OPERATION WITH BEYOND-THE-RAILS INPUT
Power Dissipation
With the high-output drive capability of the EL5210 and
EL5410 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:
