EL2344

Triple Low-Power 60MHz Unity-Gain

Stable Op Amp

The EL2344 is a triple version of the

popular EL2044. It is a high speed, low

power, low cost monolithic operational

amplifier built on Elantec’s proprietary complementary

bipolar process. The EL2344 is unity-gain stable and feature

a 325V/µs slew rate and 60MHz gain-bandwidth product

while requiring only 5.2mA of supply current per amplifier.

The power supply operating range of the EL2344 is from

±18V down to as little as ±2V. For single-supply operation,

the EL2344 operates from 36V down to as little as 2.5V. The

excellent power supply operating range of the EL2344

makes it an obvious choice for applications on a single +5V

or +3V supply.

The EL2344 also features an extremely wide output voltage

operation at +5V, output voltage swing is an excellent 0.3V to

At a gain of +1, the EL2344 has a -3dB bandwidth of

120MHz with a phase margin of 50°. It can drive unlimited

load capacitance, and because of its conventional voltage-

feedback topology, the EL2344 allows the use of reactive or

non-linear elements in their feedback network. This

versatility combined with low cost and 75mA of output-

current drive makes the EL2344 an ideal choice for price-

sensitive applications requiring low power and high speed.
