General Description

The EL2244C/EL2444C are dual and quad versions of the popular

EL2044C. They are high speed, low power, low cost monolithic oper-

ational 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

±18V 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 volt-

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

capacitance, and because of their conventional voltage-feedback

topology, the EL2244C/EL2444C allow the use of reactive or non-lin-

ear 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.
