EL2044

Low Power/Low Voltage 120MHz Unity-

Gain Stable Operational Amplifier

The EL2044 is a high speed, low

power, low cost monolithic operational

amplifier built on Elantec's proprietary

complementary bipolar process. The EL2044 is unity-gain

stable and features a 325V/µs slew rate and 120MHz gain-

bandwidth product while requiring only 5.2mA of supply

current.

The power supply operating range of the EL2044 is from

±18V down to as little as ±2V. For single-supply operation,

the EL2044 operates from 36V down to as little as 2.5V. The

excellent power supply operating range of the EL2044

makes it an obvious choice for applications on a single +5V

supply.

The EL2044 also features an extremely wide output voltage

operation at +5V, output voltage swing is an excellent 0.3V

At a gain of +1, the EL2044 has a -3dB bandwidth of

120MHz with a phase margin of 50°. Because of its

conventional voltage-feedback topology, the EL2044 allows

the use of reactive or non-linear elements in its feedback

network. This versatility combined with low cost and 75mA of

output-current drive makes the EL2044 an ideal choice for

price-sensitive applications requiring low power and high

speed.

The EL2044 is available in the 8-pin SO and 8-pin PDIP

packages and operates over the full -40°C to +85°C

temperature range.

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.
