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