The EL2044C is a high speed, low power, low cost monolithic operational amplifier built on Elantec's proprietary complementary bipolar process. The EL2044C is unity-gain stable and features a 325V/s slew rate and 120MHz gain-bandwidth product while requiring only 5.2 mA of supply current.

The power supply operating range of the EL2044C is from ±18V down to as little as ±2V. For single-supply operation, the EL2044C operates from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2044C makes it an obvious choice for applications on a single +5V supply.

The EL2044C also features an extremely wide output voltage swing of ±13.6V with VS = ±15V and RL = 1000W. At ±5V, output voltage swing is a wide ±3.8V with RL = 500W and ±3.2V with RL = 150W. Furthermore, for single-supply operation at +5V, output voltage swing is an excellent 0.3V to 3.8V with RL = 500W.

At a gain of +1, the EL2044C has a -3dB bandwidth of 120MHz with a phase margin of 50°. It can drive unlimited load capacitance, and because of its conventional voltage-feedback topology, the EL2044C allows the use of reactive or non-linear elements in its feedback network. This versatility combined with low cost and 75mA of outputcurrent drive makes the EL2044C an ideal choice for price-sensitive applications requiring low power and high speed.
