EL2250, EL2450

125MHz Single Supply Dual/Quad Op Amps

DATASHEET

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.

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.
