EL2044
FN7029.1
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
swing of ±13.6V with V_S = ±15V and R_L = 1kΩ. At ±5V,
output voltage swing is a wide ±3.8V with R_L = 500Ω and
±3.2V with R_L = 150Ω. Furthermore, for single-supply
operation at +5V, output voltage swing is an excellent 0.3V
to 3.8V with R_L = 500Ω.
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.
