Ultra-Low Noise, Low Power, Wideband
Amplifier
The EL2125 is an ultra-low noise, wideband amplifier that
runs on half the supply current of competitive parts. It is
intended for use in systems such as ultrasound imaging
where a very small signal needs to be amplified by a large
amount without adding significant noise. Its low power
dissipation enables it to be packaged in the tiny SOT-23
package, which further helps systems where many input
channels create both space and power dissipation problems.
The EL2125 is stable for gains of 10 and greater and uses
traditional voltage feedback. This allows the use of reactive
elements in the feedback loop, a common requirement for
many filter topologies. It operates from ±2.5V to ±15V
supplies and is available in the 5 Ld SOT-23 and 8 Ld SOIC
packages.
The EL2125 is fabricated using Elantec’s proprietary
complementary bipolar process, and is specified for
operation from -45°C to +85°C.
Ordering Information
NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
