Dual/Quad Low-Power 120MHz Unity-Gain
Stable Op Amp
The EL2244 and EL2444 are dual and
quad versions of the popular EL2044.
They are high speed, low power, low
cost monolithic operational amplifiers built on Elantec's
proprietary complementary bipolar process. The EL2244
and EL2444 are unity-gain stable and feature a 325V/µs
slew rate and 120MHz gain-bandwidth product while
requiring only 5.2mA of supply current per amplifier.
The power supply operating range of the EL2244 and
EL2444 is from ±18V down to as little as ±2V. For single-
supply operation, the EL2244 and EL2444 operate from 36V
down to as little as 2.5V. The excellent power supply
operating range of the EL2244 and EL2444 makes them an
obvious choice for applications on a single +5V or +3V
supply.
The EL2244 and EL2444 also feature an extremely wide
output voltage swing of ±13.6V with VS = ±15V and RL=1k.
At ±5V, output voltage swing is a wide ±3.8V with RL = 500
and ±3.2V with RL = 150. Furthermore, for single-supply
operation at +5V, output voltage swing is an excellent 0.3V to
3.8V with RL = 500.
At a gain of +1, the EL2244 and EL2444 have a -3dB
bandwidth of 120MHz with a phase margin of 50°. Because
of their conventional voltage-feedback topology, the EL2244
and EL2444 allow the use of reactive or non-linear elements
in their feedback network. This versatility combined with low
cost and 75mA of output-current drive make the EL2244 and
EL2444 an ideal choice for price-sensitive applications
requiring low power and high speed.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
