EL2044

® EL2044 Data Sheet August 16, 2004 FN7029.1 Low Power/Low Voltage 120MHz UnityGain 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 gainbandwidth 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 VS = ±15V and RL = 1kΩ. At ±5V, output voltage swing is a wide ±3.8V with RL = 500Ω and ±3.2V with RL = 150Ω. Furthermore, for single-supply operation at +5V, output voltage swing is an excellent 0.3V to 3.8V with RL = 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°...
