EL2045

Low-Power 100MHz Gain-of-2 Stable Operational Amplifier

DATASHEET

The EL2045 is a high speed, low power, low cost monolithic

operational amplifier built on Elantec's proprietary

complementary bipolar process. The EL2045 is gain-of-2

stable and features a 275V/µs slew rate and 100MHz gain-

bandwidth at gain-of-2 while requiring only 5.2mA of supply

current.

The power supply operating range of the EL2045 is from

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

the EL2045 operates from 36V down to as little as 2.5V. The

excellent power supply operating range of the EL2045

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

or +3V supply.

The EL2045 also features an extremely wide output voltage

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

At a gain of +2, the EL2045 has a -3dB bandwidth of

100MHz with a phase margin of 50°. Because of its

conventional voltage-feedback topology, the EL2045 allows

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

network. This versatility combined with low cost and 75mA of

output-current drive makes the EL2045 an ideal choice for

price-sensitive applications requiring low power and high

speed.
