They are high speed, low power, low cost monolithic operational amplifiers built on Elantec's proprietary plementary bipolar process. The EL2245C/EL2445C are gain-of-2 stable and feature a 275V/µs slew rate and 100MHz bandwidth at gain-of-2 while requiring only 5.2m A of supply current per amplifier. The power supply operating range of the EL2245C/EL2445C is from ±18V down to as little as ±2V. For single-supply operation, the EL2245C/EL2445C operate from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2245C/EL2445C makes them an obvious choice for applications on a single +5V or +3V supply. The EL2245C/EL2445C also feature an extremely wide output voltage swing of ±13.6V with VS = ±15V and RL = 1000 Ω. 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 +2, the EL2245C/EL2445C have a -3d B bandwidth of 100MHz with a phase margin of 50°. They can drive unlimited load capacitance, and because of their conventional voltage-feedback topology, the EL2245C/EL2445C allow the use of reactive or non-linear elements in their feedback network. This versatility bined with low cost and 75m A of output-current drive make the EL2245C/EL2445C an ideal choice for price-sensitive applications...
