EL2344
Triple Low-Power 60MHz Unity-Gain
Stable Op Amp
The EL2344 is a triple version of the
popular EL2044. It is a high speed, low
power, low cost monolithic operational
amplifier built on Elantec's proprietary complementary
bipolar process. The EL2344 is unity-gain stable and feature
a 325V/s slew rate and 60MHz gain-bandwidth product
while requiring only 5.2mA of supply current per amplifier.
The power supply operating range of the EL2344 is from
18V down to as little as 2V. For single-supply operation,
the EL2344 operates from 36V down to as little as 2.5V. The
excellent power supply operating range of the EL2344
makes it an obvious choice for applications on a single +5V
or +3V supply.
The EL2344 also features an extremely wide output voltage
swing of 13.6V with V
S
= 15V and R
L
= 1000
. 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 EL2344 has a -3dB bandwidth of
120MHz with a phase margin of 50. It can drive unlimited
load capacitance, and because of its conventional voltage-
feedback topology, the EL2344 allows the use of reactive or
non-linear elements in their feedback network. This
versatility combined with low cost and 75mA of output-
current drive makes the EL2344 an ideal choice for price-
sensitive applications requiring low power and high speed.
