125MHz Single Supply Dual/Quad Op Amps
Features
The EL2250/EL2450 are part of a family of the electronics
industry’s 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.

• Specified for +3V, +5V, or ±5V 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
are 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.
