EL2245, EL2445

Dual/Quad Low-Power 100MHz Gain-of-2

Stable Op Amp

The EL2245 and EL2445 are dual and

quad versions of the popular EL2045.

They are high speed, low power, low

cost monolithic operational amplifiers built on Elantec's

proprietary complementary bipolar process. The EL2245

and EL2445 are gain-of-2 stable and feature a 275V/µs slew

rate and 100MHz bandwidth at gain-of-2 while requiring only

5.2mA of supply current per amplifier.

The power supply operating range of the EL2245 and

EL2445 is from ±18V down to as little as ±2V. For single-

supply operation, the EL2245 and EL2445 operate from 36V

down to as little as 2.5V. The excellent power supply

operating range of the EL2245 and EL2445 makes them an

obvious choice for applications on a single +5V or +3V

supply.

The EL2245 and EL2445 also feature an extremely wide

single-supply operation at +5V, output voltage swing is an

At a gain of +2, the EL2245 and EL2445 have a -3dB

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

of their conventional voltage-feedback topology, the EL2245

and EL2445 allow the use of reactive or non-linear elements

in their feedback network. This versatility combined with low

cost and 75mA of output-current drive make the EL2245 and

EL2445 an ideal choice for price-sensitive applications

requiring low power and high speed.
