DATASHEET EL2125 FN7045 Rev 3.00 Ultra-Low Noise, Low Power, Wideband Amplifier May 4, 2007 The EL2125 is an ultra-low noise, wideband amplifier that Features runs on half the supply current of competitive parts. It is Voltage noise of only 0.83nV/ Hz intended for use in systems such as ultrasound imaging where a very small signal needs to be amplified by a large Current noise of only 2.4pA/Hz amount without adding significant noise. Its low power 200V offset voltage dissipation enables it to be packaged in the tiny SOT-23 175MHz -3dB BW for A = 10 package, which further helps systems where many input V channels create both space and power dissipation problems. Low supply current - 10mA The EL2125 is stable for gains of 10 and greater and uses SOT-23 package available traditional voltage feedback. This allows the use of reactive 2.5V to 15V operation elements in the feedback loop, a common requirement for many filter topologies. It operates from 2.5V to 15V Pb-Free Plus Anneal Available (RoHS Compliant) supplies and is available in the 5 Ld SOT-23 and 8 Ld SOIC Applications packages. Ultrasound input amplifiers The EL2125 is fabricated using Elantecs proprietary complementary bipolar process, and is specified for Wideband instrumentation operation from -45C to +85C.
