Elantec EL5410CR 30mhz rail-to-rail input-output op amp Datasheet

30MHz Rail-to-Rail Input-Output Op Amps
Features
General Description
• 30MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
• Low supply current (per amplifier)
= 2.5mA
• High slew rate = 33V/µs
• Unity-gain stable
• Beyond the rails input capability
• Rail-to-rail output swing
• Available in both standard and
space-saving fine pitch packages
The EL5210C and EL5410C are low power, high voltage rail-to-rail
input-output amplifiers. The EL5210C contains two amplifiers in one
package and the EL5410C contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 2.5mA per
amplifier, the EL5410C and EL5210C have a bandwidth of 30MHz -(-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 EL5410C and EL5210C 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 high speed filtering and signal conditioning application. Other applications include
battery power, portable devices, and anywhere low power consumption is important.
The EL5410C is available in a space-saving 14-Pin TSSOP package,
as well as the industry-standard 14-Pin SOIC. The EL5210C is available in the 8-Pin MSOP and 8-Pin SOIC packages. Both feature a
standard operational amplifier pin out. These amplifiers operate over a
temperature range of -40°C to +85°C.

Output
The EL5210C and EL5410C 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
EL5210C and EL5410C ideal for a wide range of general-purpose applications. Connected in voltage follower
mode and driving a load of 1kΩ and 12pF, the EL5210C
and EL5410C have a -3dB bandwidth of 30MHz while
maintaining a 33V/µS slew rate. The EL5210C is a dual
amplifier while the EL5410C is a quad amplifier.
Operating Voltage, Input, and Output
The EL5210C and EL5410C 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
EL5210C and EL5410C 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.
Figure 1. Operation with Rail-to-Rail Input and
Output
Short Circuit Current Limit
The EL5210C and EL5410C 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.
The input common-mode voltage range of the EL5210C
and EL5410C extends 500mV beyond the supply rails.
The output swings of the EL5210C and EL5410C 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 1kΩ load
Output Phase Reversal
The EL5210C and EL5410C 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.

0.6V, electrostatic protection diodes placed in the input

With the high-output drive capability of the EL5210C
and EL5410C 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.
If we set the two PDMAX equations equal to each other,
we can solve for RLOADi to avoid device overheat. Figure 3 and Figure 4 provide a convenient way to see if the
device will overheat. The maximum safe power dissipation 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 shown in Figure 3 and Figure 4.
The maximum power dissipation allowed in a package is
determined according to:
T JM AX – T A MA X
P D MAX = -------------------------------------------Θ JA
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
12
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 EL5210C and EL5410C can drive a wide range of
capacitive loads. As load capacitance increases, however, the -3dB bandwidth of the device will decrease and
the peaking increase. The amplifiers drive 10pF loads in
parallel with 1kΩ with just 1.2dB of peaking, and 100pF
with 6.5dB 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 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 150Ω and 10nF are typical. The advantage of a snubber is that it does not draw any DC load current or
reduce the gain

The EL5210C and EL5410C 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 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 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.
