EL2244, EL2444
Dual/Quad Low-Power 120MHz Unity-Gain
Stable Op Amp
The EL2244 and EL2444 are dual and quad versions of the
popular EL2044. They are high speed, low power, low cost
monolithic operational amplifiers built on Elantec's
proprietary complementary bipolar process. The EL2244
and EL2444 are unity-gain stable and feature a 325V/s
slew rate and 120MHz gain-bandwidth product while
requiring only 5.2mA of supply current per amplifier.
The power supply operating range of the EL2244 and
EL2444 is from 18V down to as little as 2V. For single-
supply operation, the EL2244 and EL2444 operate from 36V
down to as little as 2.5V. The excellent power supply
operating range of the EL2244 and EL2444 makes them an
obvious choice for applications on a single +5V or +3V
supply.
The EL2244 and EL2444 also feature an extremely wide
output voltage swing of 13.6V with V
S
= 15V and R
L
=1k
.
At 5V, output voltage swing is a wide 3.8V with R
L
= 500
and 3.2V with R
L
= 150
. Furthermore, for single-supply
operation at +5V, output voltage swing is an excellent 0.3V
to 3.8V with R
L
= 500
.
At a gain of +1, the EL2244 and EL2444 have a -3dB
bandwidth of 120MHz with a phase margin of 50. Because
of their conventional voltage-feedback topology, the EL2244
and EL2444 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 EL2244 and
EL2444 an ideal choice for price-sensitive applications
requiring low power and high speed.
