Description

The EL2045 is a high speed, low power, low cost monolithic operational amplifier built on Elantec's proprietary complementary bipolar process. The EL2045 is gain-of-2 stable and features a 275V/s slew rate and 100MHz gainbandwidth at gain-of-2 while requiring only 5.2mA of supply current. The power supply operating range of the EL2045 is from ±18V down to as little as ±2V. For single-supply operation, the EL2045 operates from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2045 makes it an obvious choice for applications on a single +5V or +3V supply. The EL2045 also features 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 +2, the EL2045 has a -3dB bandwidth of 100MHz with a phase margin of 50. Because of its conventional voltage-feedback topology, the EL2045 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 EL2045 an ideal choice for price-sensitive applications requiring low power and high speed.
