General Description
The EL2125C 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 SOT23
package, which further helps systems where many input channels cre-
ate both space and power dissipation problems.
The EL2125C is stable for gains of 10 and greater and uses traditional
voltage feedback. This allows the use of reactive elements in the feed-
back loop, a common requirement for many filter topologies. It
operates from ±2.5V to ±15V supplies and is available in a 5-pin
SOT23 package and 8-pin SO and 8-pin PDIP packages.
The EL2125C is fabricated in Elantec’s proprietary complementary
bipolar process, and is specified for operation from -45°C to +85°C.
