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

5.2mA 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

is a wide ±3.8V with R

more, 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°. Because of its conventional voltage-feedback

topology, the EL2044C allows the use of reactive or non-linear ele-

ments in its feedback network. 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.

The EL2044C is available in the 8-pin SO and 8-pin PDIP packages

and operates over the full -40°C to +85°C temperature range.
