General Description
The EL2244C/EL2444C are dual and quad versions of the popular EL2044C. They are high speed, low power, low cost monolithic opera t i o n a l amplifiers built on Elantec's proprietary complementary bipolar process. The EL2244C/EL2444C are unity-gain stable and feature a 325V/µs slew rate and 120MHz gain-bandwidth product while requiring only 5.2mA of supply current per amplifier. The power supply operating range of the EL2244C/EL2444C is from ± 1 8 V down to as little as ±2V. For single-supply operation, the EL2244C/EL2444C operate from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2244C/EL2444C makes them an obvious choice for applications on a single +5V or +3V supply. The EL2244C/EL2444C also feature an extremely wide output voltage swing of ±13.6V with VS = ±15V and RL = 1000. 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 +1, the EL2244C/EL2444C have a -3dB bandwidth of 120MHz with a phase margin of 50°. They can drive unlimited load c a p a c i t a n c e , and because of their conventional voltage-feedback topology, the EL2244C/EL2444C allow the use of reactive or non-linear elements in their feedback network. This versatility combined with low cost and 75mA of output-current drive make the EL2244C/EL2444C an ideal choice for price-sensitive applications requiring low power and high speed.

1. Slew rate is measured on rising edge 2. For VS = ±15V, VOUT = 20VPP. For VS = ±5V, VOUT = 5VPP. Full-power bandwidth is based on slew rate measurement using: FPBW = SR/(2 * Vpeak). 3. Video Performance measured at VS = ±15V, AV = +2 with 2 times normal video level across RL = 150. This corresponds to standard video levels across a back-terminated 75 load. For other values of RL, see curves.
