EL2245C, EL2445C

Dual/Quad Low-Power 100MHz Gain-of-2 Stable Op Amp

General Description

The EL2245C and EL2445C are dual and quad versions of the popular

EL2045C. They are high speed, low power, low cost monolithic oper-

ational amplifiers built on Elantec's proprietary complementary

bipolar process. The EL2245C and EL2445C 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 EL2245C and EL2445C is

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

EL2245C and EL2445C operate from 36V down to as little as 2.5V.

The excellent power supply operating range of the EL2245C and

EL2445C makes them an obvious choice for applications on a single

+5V or +3V supply.

The EL2245C and EL2445C also feature an extremely wide output

voltage swing of ±13.6V with V

put voltage swing is a wide ±3.8V with R

= 150Ω. Furthermore, for single-supply operation at +5V, output volt-

age swing is an excellent 0.3V to 3.8V with R

At a gain of +2, the EL2245C and EL2445C have a -3dB bandwidth of

100MHz with a phase margin of 50°. Because of their conventional

voltage-feedback topology, the EL2245C and EL2445C allow the use

of reactive or non-linear elements in their feedback network. This ver-

satility combined with low cost and 75mA of output-current drive

make the EL2245C and EL2445C an ideal choice for price-sensitive

applications requiring low power and high speed.
