EL2044C

Low Power/Low Voltage 120MHz Unity-Gain Stable Operational Amplifier

General Description

The EL2044C is a high speed, low power, low cost monolithic opera-

tional amplifier built on Elantec's proprietary complementary bipolar

process. The EL2044C is unity-gain stable and features a 325V/µs

slew rate and 120MHz gain-bandwidth product while requiring only

5.2 mA of supply current.

The power supply operating range of the EL2044C is from ±18V

down to as little as ±2V. For single-supply operation, the EL2044C

operates from 36V down to as little as 2.5V. The excellent power sup-

ply operating range of the EL2044C makes it an obvious choice for

applications on a single +5V supply.

The EL2044C also features an extremely wide output voltage swing of

±13.6V with V

swing is a wide ±3.8V with R

Furthermore, for single-supply operation at +5V, output voltage swing

is an excellent 0.3V to 3.8V with R

At a gain of +1, the EL2044C 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 EL2044C

allows the use of reactive or non-linear elements in its feedback net-

work. This versatility combined with low cost and 75mA of output-

current drive makes the EL2044C an ideal choice for price-sensitive

applications requiring low power and high speed.
