125MHz Single Supply Dual/Quad Op Amps
The EL2250/EL2450 are part of a family of the electronics
industries fastest single supply op amps available. Prior
single supply op amps have generally been limited to
bandwidths and slew rates to that of the EL2250/EL2450.
The 125MHz bandwidth, 275V/µs slew rate, and
0.05%/0.05° differential gain/differential phase makes this
part ideal for single or dual supply video speed applications.
With its voltage feedback architecture, this amplifier can
accept reactive feedback networks, allowing them to be
used in analog filtering applications. The inputs can sense
signals below the bottom supply rail and as high as 1.2V
below the top rail. Connecting the load resistor to ground
and operating from a single supply, the outputs swing
completely to ground without saturating. The outputs can
also drive to within 1.2V of the top rail. The EL2250/EL2450
will output ±100mA and will operate with single supply
voltages as low as 2.7V, making them ideal for portable, low
power applications.
The EL2250/EL2450 are available in PDIP and SO
packages in industry standard pin outs. Both parts operate
over the industrial temperature range of -40°C to +85°C, and
arewww.DataSheet4U.com part of a family of single supply op amps. For single
amplifier applications, see the EL2150/EL2157. For dual and
triple amplifiers with power down and output voltage clamps,
see the EL2257/EL2357.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.

The maximum power dissipation allowed in a package is
determined according to [1]:
PDMAX = T----J---M-----A----X--θ---–J---A--T----A---M-----A----X--
FIGURE 2.
Short Circuit Current Limit
The EL2250/EL2450 have internal short circuit protection
circuitry that protect it in the event of its output being shorted
to either supply rail. This limit is set to around 100mA
nominally and reduces with increasing junction temperature.
It is intended to handle temporary shorts. If an output is
shorted indefinitely, the power dissipation could easily
increase such that the part will be destroyed. Maximum
reliability is maintained if the output current never exceeds
±90mA. A heat sink may be required to keep the junction
temperature below absolute maximum when an output is
shorted indefinitely.
Power Dissipation
With the high output drive capability of the EL2250/EL2450,
it is possible to exceed the 150°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 power-supply
voltages, load conditions, or package type need to be
modified for the EL2250/EL2450 to remain in the safe
operating area.
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 load, or

where:
N = Number of amplifiers
VS = Total Supply Voltage
ISMAX = Maximum Supply Current per amplifier
VOUT = Maximum Output Voltage of the Application
RL = Load Resistance tied to Ground
If we set the two PDMAX equations, [1] & [2], equal to each
other, and solve for VS, we can get a family of curves for
various loads and output voltages according to [3]:
VS
=
-R---------L----------×--------(------T--------J--N----M--------×A--------X--θ------J--–----A------T--------A--------M---------A-------X---------)----+-----(--V-----O----U----T----)

Figures 3 through 6 below show total single supply voltage
VS vs. RL for various output voltage swings for the PDIP and
SO packages. The curves assume WORST CASE
conditions of TA = +85°C and IS = 6.5mA per amplifier.
